Description
string 
pg_escape_string ( string data )
   pg_escape_string() escapes a string for
   insertion into the database.  It returns an escaped string in the
   PostgreSQL format. Use of this function is recommended instead of
   addslashes().  If the type of the column
   is bytea, pg_escape_bytea() must be used
   instead.
  
Note: 
    This function requires PostgreSQL 7.2 or later.
