Postgres Errors When Enabling Auction Component

Greetings,

After installing the ecommerce module and running update.php I enabled the core components etc... as instructed in the documentation for the module. When enabling the auction component I received these errors.

query: CREATE TABLE ec_auction_bid ( nid integer NOT NULL default '0', uid integer NOT NULL default '0', bid decimal(10,2) NOT NULL default '0.00', created integer NOT NULL default '0', KEY nid (nid) ) in /includes/database.pgsql.inc on line 144.

pg_query() [function.pg-query]: Query failed: ERROR: syntax error at or near "(" LINE 6: KEY nid (nid) ^ in /includes/database.pgsql.inc on line 125.

Regards,
Jason
