Where is the INSERTed data coming from? - Is it coming from data
submitted by GET or POST? - if so, is magic_quotes_gpc turned on? If it
is, this could explain what you're seeing.

BTW, it's much better to use parametrised queries - look up
pg_query_params in the PHP docs. This looks after all quoting for you
automatically, and prevents SQL injection attacks.
