Description:
------------
when using pg_insert(),everything works, but when the program
terminates it reports a "Segmentation fault".

Data are properly inserted into table,
db connection closed ok. too.

create a small table

create table test (regn text, mtow numeric(6,2), tonbl timestamp(0) with time zone);

Actually, just using pg_convert() on the array causes the same segmentation fault to be reported. Without even trying to insert the data.

Reproduce code:
---------------
Use some data
$data = array('regn' => 'defi', 
              'mtow' =>  23.2,
              'tonbl' => '2008-05-15T16:15:16+00');

insert using:
$db = pg_connect("dbname=foo");
$res = pg_insert($db, 'test', $data);
pg_close($db);

My php5 binary doesn't have debug symbols enabled, it seems.
Anyway, I ran the code again from within the debuger and got this
output:

bash%gdb /usr/bin/php5
