• Correctly identify columns that are of a range type or domain type over a composite type or domain type being searched for
• Prevent crash when passing fixed-length pass-by-reference data types to parallel worker processes
• Fix crash in pg_restore when using parallel mode and using a list file to select a subset of items to restore
• Change ecpg’s parser to allow RETURNING clauses without attached C variables
• Change ecpg’s parser to recognize backslash continuation of C preprocessor command lines
• Improve selection of compiler flags for PL/Perl on Windows
