JDBC 42.2.3 Released

The JDBC project is proud to announce the latest version 42.2.3. This release fixes some annoyances such as:

• Reduce the severity of the error log messages when an exception is re-thrown. The error will be thrown to caller to be dealt with so no need to log at this verbosity by pgjdbc
• Support parenthesis in {oj ...} JDBC escape syntax
• getString for PGObject-based types returned "null" string instead of null
• Field metadata cache can be disabled via databaseMetadataCacheFields=0
• Properly encode special symbols in passwords in BaseDataSource
• Adjust date, hour, minute, second when rounding nanosecond part of a timestamp
• Encode URL parameters in BaseDataSource

As well as some performance enhancements:

• reduce memory allocations in query cache
• reduce memory allocations in SQL parser
