When trying to call pg_convert for a table with an interval column, php throws a warning indicating that it can not compile the regex used to match interval values.

The regex is on line 3999 of ext/pgsql/pgsql.c  I think the regex is missing a ')' as the second last character.  

However, this regex also contains other semantic errors and rejects valid values as well as accepts some bogus ones.  I have written a replacement regex and created a patch, available at

Reproduce code:

$con = pg_connect("dbname=database");
$arr = array("interval_col" => "1 day");

// Presumably tmp_table contains a column 'interval_col' with type 'interval'
$sql = pg_convert($con, "tmp_table", $arr);

echo "\n";


Expected result:
    [interval_col] => '1 day'

Actual result:
Notice: pg_convert(): '1 day' does not match with '^[+-]{0,1}[ \t]+((second|seconds|minute|minute|hour|hour|day|days|week|weeks|month|monthes|year|years|decade|decades|century|centuries|millennium|millenniums){1,1}[ \t]+)+([ \t]+ago){0,1}$' in pg_convert.php on line 8

Warning: pg_convert(): Cannot compile regex in pg_convert.php on line 8

Notice: pg_convert(): Expects NULL or string for PostgreSQL interval field (interval_col) in pg_convert.php on line 8

These probably all get fixed in the same place, but just in case:

Ditto for pg_insert(), haven't tried pg_delete() or pg_update()...
