PostgreSQL PHP & Error handling

Hi All

Continuing my research of Serializable transaction I wanted to conduct a
test of running two querys expecting that the second query will return:
"ERROR: Can't serialize access due to concurrent update"

The only way I could check what is the last error was pg_last_error( $conn )
while it seems that pg_result_error( $res ) & pg_result_status( $res )
should be more reliable as they use the query result resource.

But the main problem is that pg_query() return false on error so I cant use
the returned value what make the little useless :(

any one know some other way to intercept errors ?
