Here is the results:

draft=# SELECT version();

version
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
PostgreSQL 9.1.24 on x86_64-apple-darwin, compiled by
i686-apple-darwin10-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc.
build 5658) (LLVM build 2335.6), 64-bit
(1 row)

Is there a way to get just "9.1.24" without everything else?

Or maybe the server can perform parsing for me?

Thank you.
