OPTIONAL
SYNOPSIS
        string pg_conv_string(string str)

DESCRIPTION
        Convert the string <str> into a string that is correctly interpretated
        for usage as a string in pg_query(), e.g. ' is replaced with \' and so
        on.

        The function is available only if the driver is compiled with
        PostgreSQL support. In that case, __PGSQL__ is defined.

        The efun triggers a privilege violation ("pgsql", "pg_connect").
