Try to make a database connection to the given URL. The driver should return "null" if it + * realizes it is the wrong kind of driver to connect to the given URL. This will be common, as + * when the JDBC driverManager is asked to connect to a given URL, it passes the URL to each + * loaded driver in turn.

+ * + *

The driver should raise an SQLException if it is the right driver to connect to the given URL, + * but has trouble connecting to the database.

+ * + *

The java.util.Properties argument can be used to pass arbitrary string tag/value pairs as + * connection arguments.

+ * + *
    + *
  • user - (required) The user to connect as
    • + *
  • password - (optional) The password for the user
    • + *
  • ssl -(optional) Use SSL when connecting to the server
    • + *
  • readOnly - (optional) Set connection to read-only by default
    • + *
  • charSet - (optional) The character set to be used for converting to/from + * the database to unicode. If multibyte is enabled on the server then the character set of the + * database is used as the default, otherwise the jvm character encoding is used as the default. + * This value is only used when connecting to a 7.2 or older server.
    • + *
  • loglevel - (optional) Enable logging of messages from the driver. The value is an integer + * from 0 to 2 where: OFF = 0, INFO =1, DEBUG = 2 The output is sent to + * DriverManager.getPrintWriter() if set, otherwise it is sent to System.out.
    • + *
  • compatible - (optional) This is used to toggle between different functionality + * as it changes across different releases of the jdbc driver code. The values here are versions + * of the jdbc client and not server versions. For example in 7.1 get/setBytes worked on + * LargeObject values, in 7.2 these methods were changed to work on bytea values. This change in + * functionality could be disabled by setting the compatible level to be "7.1", in which case the + * driver will revert to the 7.1 functionality.
    • + *
+ * + *

Normally, at least "user" and "password" properties should be included in the properties. For a + * list of supported character encoding , see + * http://java.sun.com/products/jdk/1.2/docs/guide/internat/encoding.doc.html Note that you will + * probably want to have set up the Postgres database itself to use the same encoding, with the + * {@code -E } argument to createdb.

Returns the current values of all parameters reported by the server.

+ * + *

PostgreSQL reports values for a subset of parameters (GUCs) to the client + * at connect-time, then sends update messages whenever the values change + * during a session. PgJDBC records the latest values and exposes it to client + * applications via getParameterStatuses().

+ * + *

PgJDBC exposes individual accessors for some of these parameters as + * listed below. They are more backwards-compatible and should be preferred + * where possible.

+ * + *

Not all parameters are reported, only those marked + * GUC_REPORT in the source code. The pg_settings + * view does not expose information about which parameters are reportable. + * PgJDBC's map will only contain the parameters the server reports values + * for, so you cannot use this method as a substitute for running a + * SHOW paramname; or SELECT + * current_setting('paramname'); query for arbitrary parameters.

+ * + *

Parameter names are case-insensitive and case-preserving + * in this map, like in PostgreSQL itself. So DateStyle and + * datestyle are the same key.

+ * + *

+ * As of PostgreSQL 11 the reportable parameter list, and related PgJDBC + * interfaces or assessors, are: + *

+ * + *
    + *
  • + * application_name - + * {@link java.sql.Connection#getClientInfo()}, + * {@link java.sql.Connection#setClientInfo(java.util.Properties)} + * and ApplicationName connection property. + *
    • + *
  • + * client_encoding - PgJDBC always sets this to UTF8. + * See allowEncodingChanges connection property. + *
    • + *
  • DateStyle - PgJDBC requires this to always be set to ISO
    • + *
  • standard_conforming_strings - indirectly via {@link #escapeLiteral(String)}
    • + *
  • + * TimeZone - set from JDK timezone see {@link java.util.TimeZone#getDefault()} + * and {@link java.util.TimeZone#setDefault(TimeZone)} + *

Every connection has a single QueryExecutor implementation associated with it. This object + * provides:

  • factory methods for Query objects ({@link #createSimpleQuery(String)} and + * {@link #createQuery(String, boolean, boolean, String...)}) + *
  • execution methods for created Query objects ( + * {@link #execute(Query, ParameterList, ResultHandler, int, int, int)} for single queries and + * {@link #execute(Query[], ParameterList[], BatchResultHandler, int, int, int)} for batches of queries) + *
  • a fastpath call interface ({@link #createFastpathParameters} and {@link #fastpathCall}). + *

Query objects may represent a query that has parameter placeholders.

To do it correctly in all cases would seem to require a + // separate send or receive thread as we can only do the Sync-and-read-results + // operation at particular points, and also as we don't really know how much data + // the server is sending. + // + // Our message size estimation is coarse, and disregards asynchronous + // notifications, warnings/info/debug messages, etc, so the response size may be + // quite different from the 250 bytes assumed here even for queries that don't + // return data. + // + // See github issue #194 and #195 . + // + // Assume 64k server->client buffering, which is extremely conservative.

Escapes a given text value as a literal, wraps it in single quotes, casts it to the + * to the given data type, and finally wraps the whole thing in parentheses.

+ * + *

For example, "123" and "int4" becomes "('123'::int)"

+ * + *

The additional parentheses is added to ensure that the surrounding text of where the + * parameter value is entered does modify the interpretation of the value.

+ * + *

For example if our input SQL is: SELECT ?b

Using a parameter value of '{}' and type of json we'd get:

REMEMBER to close() the resultset after calling this!!

Implementation note about function name lookups:

+ * + *

PostgreSQL stores the function id's and their corresponding names in the pg_proc table.

The org.postgresql.largeobject.LargeObject class performs a query upon it's startup, and passes + * the returned ResultSet to the addFunctions() method here.

+ * + *

Once this has been done, the LargeObject api refers to the functions by name.

+ * + *

Don't think that manually converting them to the oid's will work. Ok, they will for now, but + * they can change during development (there was some discussion about this for V7.0), so this is + * implemented to prevent any unwarranted headaches in the future.

Provides a SSLSocketFactory that authenticates the remote server against an explicit pre-shared + * SSL certificate. This is more secure than using the NonValidatingFactory as it prevents "man in + * the middle" attacks. It is also more secure than relying on a central CA signing your server's + * certificate as it pins the server's certificate.

+ * + *

This class requires a single String parameter specified by setting the connection property + * sslfactoryarg. The value of this property is the PEM-encoded remote server's SSL + * certificate.

+ * + *

Where the certificate is loaded from is based upon the prefix of the sslfactoryarg property. + * The following table lists the valid set of prefixes.
