http://jdbc.postgresql.org/changes.htmlJDBC Driver Changesen-ushttp://jdbc.postgresql.org/changes.html fix by jurka : Don't list toast table types in the output of DatabaseMetaData.getTypeInfo. http://jdbc.postgresql.org/changes.html add by jurka : Add support for GSSAPI authentication. http://jdbc.postgresql.org/changes.html fix by jurka : The Statement and Connection proxies used for connection pooling code relied on the underlying real connection and statement code for equals and hashcode support. When the proxies are closed we discard the references to the real objects, so we can't rely on them for this support because we'll get a NullPointerException. Thanks to Radu Buzila.http://jdbc.postgresql.org/changes.html add by jurka : Implement support for generated keys for PreparedStatements in addition to the earlier support for plain Statements. http://jdbc.postgresql.org/changes.html fix by jurka : Not all datatypes use a comma for the array element delimiter. Lookup the appropriate delimiter in the system catalogs. http://jdbc.postgresql.org/changes.html fix by jurka : DatabaseMetaData.getColumns was broken for the JDBC 3 and 4 drivers when running against 7.2 or older servers. http://jdbc.postgresql.org/changes.html fix by jurka : Retrieve columns' default values from pg_attrdef.adbin rather than adsrc because adsrc can get out of date when dependent objects are renamed while adbin stays up to date. Thanks to Dickson Guedes, Tom Lane.http://jdbc.postgresql.org/changes.html add by jurka : Speed up parsing of BigDecimal values in the common case of reasonably short, simple numbers. Thanks to Heikki Linnakangas.http://jdbc.postgresql.org/changes.html fix by jurka : Fix parsing of integer and long data. Some malformed inputs (only a negative sign) got treated as valid data. Thanks to Heiiki Linnakangas.http://jdbc.postgresql.org/changes.html add by jurka : Avoid sending extra Describe Portal messages to the server when we've already done this for the query. Caching the Field objects across executions will also speed up ResultSetMetaData calls. Thanks to Heiiki Linnakangas.http://jdbc.postgresql.org/changes.html add by jurka : Avoid sending extra Describe Statement messages to the server when we've already done this for the query. http://jdbc.postgresql.org/changes.html fix by jurka : Initialize BatchUpdateExceptions with the SQLState of the SQLException that they are wrapping. Code that inspects the SQLStates of SQLExceptions, but doesn't unwrap the nested exception will not understand the underlying cause and may make incorrect decisions about the severity of the error. Thanks to Fujii Masao.http://jdbc.postgresql.org/changes.html update by jurka : Updated Serbian translation. Thanks to Bojan Skaljac.http://jdbc.postgresql.org/changes.html update by jurka : Updated Brazilian Portuguese translation. Thanks to Euler Taveira de Oliveira.http://jdbc.postgresql.org/changes.html update by jurka : Updated Turkish translation. Thanks to Devrim Gunduz.http://jdbc.postgresql.org/changes.html add by jurka : Add a connection parameter for setting a socket read timeout. This acts like a global query timeout that shuts down the connection if exceeded. This can be used to detect dead network connections if you can reasonably estimate the upper bound of your queries. Thanks to Art Gramlich.http://jdbc.postgresql.org/changes.html fix by jurka : Initialize the prepareThreshold parameter for datasources to the same value that would be used by a non-DataSource created connection. By not setting it, it effectively turned off the use of named statments. http://jdbc.postgresql.org/changes.html add by jurka : Provide a way for the user to specify the desired length return value for metadata about types of unknown length. We've tried a number of things and can't keep everyone happy, so it's their problem now. http://jdbc.postgresql.org/changes.html add by jurka : Implement support for COPY in the JDBC driver with a non-standard postgresql CopyManager API. This provides support for both copy from the server and to the server and operating in either a source or sink mode. Thanks to Kalle Hallivuori.
