Field Detail

FORCECLIENTENC

public static final String FORCECLIENTENC

Force a Set client encoding. If this property is present, then its value is sent as a SET CLIENT_ENCODING TO command to the backend prior to any other command.

Constant Field Values

OPTIONS

public static final String OPTIONS

Additional options passed to the backend. The value supplied to this property is passed in the startup packet to the backend which appends it to the command line.

Constant Field Values

PROTOVERSION

public static final String PROTOVERSION

Protocol version to use. The value is interpreted as an integer that denotes the version number of the protocol that should be used to connect to the backend. Possible values are 0,1,2.

Constant Field Values

SETTIMEZONE

public static final String SETTIMEZONE

Specify client time zone. If this property is set, then the backend is informed of the client time zone via a call to SET TIME ZONE. If no value is specified the JVM's default time zone is transmitted.

Constant Field Values

STRICTSCHEMA

public static final String STRICTSCHEMA

Strict checking for SCHEMA parameter in DatabaseMetaData. If this property is present, the DatabaseMetaData functions will do strict checking of a supplied SCHEMA parameter. Returning empty result sets for anything but a null, as PostgreSQL does not support schemas and therefore nothing can match a non null schema pattern. If not set, the functions simply ignore the parameter.

Constant Field Values

TTY

public static final String TTY

The tty for the backend to write additional debug info to. The value supplied to this property is passed in the startup packet to the backend.

See Also:

Constant Field Values

USEASYNC

public static final String USEASYNC

Use async notification protocol. According to the protocol specification the backend can at any time send a notification packet. When using the default (polling) protocol this packet is processed only after sending out the next query. When this (key-only) property is set, the driver starts a new Thread to handle the protocol and can react immeadiately to the notification by sending out an PGNotifyEvent.

Constant Field Values

USECLIENTENC

public static final String USECLIENTENC

Override client encoding. If this property is present, then its value is used as the Java encoding name for converting text data in the protocol. No attempt is made to find out the client encoding the backend thinks it is using.

See Also:

Constant Field Values

USEDBENC

public static final String USEDBENC

Use server encoding. If this property is present, then its value will override the encoding queried from the backend.

See Also:

Constant Field Values

USESSL

public static final String USESSL

Try to establish SSL secured connection. When this property is set, the driver tries to establish an SSL secured connection to the backend. For this to work the backend has to be compiled with SSL, and the driver has to be compiled with JSSE. If the property's value is set to "force", an Exception will be thrown if the SSL secured connection cannot be established. Otherwise the driver continues on the unsecured channel. NOTE: Configure Your backend pg_hba.conf appropriately.
