Thanks. I adopted your version check for pgsql.<br>

<pre wrap="">Hi,
I am not very familiar with Postgresql.
I wrote taxonomy_access.install file, but for POSTGRESQL priot to 8.0, I
need to make a BIT_OR aggregate function.
Do you think this will work OK for pg?
if (version_compare(pg_version(), '8.0', '<')) {
// PRIOR TO POSTGRESQL 8.0: making a BIT_OR aggregate function

That has problems. Here's something that I've put together for the update
process, though it has not been incorporated yet. Then there's similar
thinking for the install process. Considering the need to know server
version numbers in several places, I hope code along the following lines
gets incorporated into database.inc:
function get_db_server_version() {
static $version;
if (isset($version)) {
return $version;
}
switch ($GLOBALS['db_type']) {
case 'mysql':
case 'mysqli':
if (function_exists('mysql_get_server_info')) {
// Since: MySQL library: 4.0.1-alpha, PHP: 4.0.5.
$version = mysql_get_server_info($GLOBALS['active_db']);
}
else {
$row = db_fetch_object(db_query('SELECT version() AS version'));
$version = $row->version;
}
$version = str_replace(array('-debug','-max','-nt','-opt'), '', $version);
break;
case 'pgsql':
/*
* Not using pg_version() because it is only available in PHP 5 and with
* PostgreSQL library: 7.4. More importantly, the 'server_version'
* is missing, at least in PHP 5.1.2.
*/
$row = db_fetch_object(db_query('SELECT version() AS version'));
$version = preg_replace('/^[^0-9]+([^ ]+).*/i', '\\1', $row->version);
break;
default:
$version = 0;
}
return $version;
}
