Re: [GENERAL] Backward compatibility

Hi, ALL,
According to the documentation PostgreSQL 9.6 (latest) supports

CREATE INDEX IF NOT EXIST

However, the version 9.4 and below supports only

CREATE INDEX.

Is there a query or a libpg function which can return the version of
the server I'm running?

And in the latter case - is there a way to check if the index exist?

I guess I will have to query "information_schema" again...
