Hi,

   Today, i've tried to install two sets of datas into a drupal 6.2
database (with pgsql). With a table prefix i've take an error like :

Warning: pg_query() [function.pg-query]: Query failed: ERROR: type
"int_unsigned" already exists in
/var/www/xxxxxx/drupal-6.2/includes/database.pgsql.inc on line 138
Warning: ERROR: type "int_unsigned" already exists query: CREATE DOMAIN
int_unsigned integer CHECK (VALUE >= 0) in

DOMAIN bigint_unsigned bigint CHECK (VALUE >= 0) in
/var/www/xxxxxx/drupal-6.2/includes/database.pgsql.inc on line 159

   Ok ... Drupal try to create data types two times ... and crash :(

   If anyone else has the same error, this patch can solve this problem :
