JDBC checkin fixing the following bugs:
Fixed support in the driver for notifications (added PGConnection.getNotifications()) - problem reported by Benjamin.Feinstein@guardent.com Worked around server problems with int8/int2 and constants; quote values when they are intended to bind to an int8/int2 column - reported by many Fixed bug in the Array interface with string parsing not handling escaped characters correctly - reported by devajx@yahoo.com Added workaround to support 'infinity' and '-infinity' for dates - reported bydmitry@openratings.com Fixed some performance issues with setBlob - reported by d.wall@computer.org Added support for using new prepared statements functionality in 7.3 (added PGStatement.setUseServerPrepare() and isUseServerPrepare() methods) Modified Files: jdbc/org/postgresql/PGConnection.java jdbc/org/postgresql/PGStatement.java jdbc/org/postgresql/core/QueryExecutor.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Connection.java jdbc/org/postgresql/jdbc1/AbstractJdbc1ResultSet.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Statement.java jdbc/org/postgresql/jdbc2/AbstractJdbc2Statement.java jdbc/org/postgresql/jdbc2/Array.java Added Files: jdbc/org/postgresql/PGNotification.java jdbc/org/postgresql/core/Notification.java
