What version of the driver are you using? Earlier versions had some
problems and this one (returning `foo_pk' for all rows) looks like one
of them.

Subject: [INTERFACES] JDBC primary keys


 Is there a way to determine all primary key columns in a given table?  Example:  CREATE TABLE foo (   bar1 int4,
bar2text,   bar3 float8,   CONSTRAINT foo_pk PRIMARY KEY ( bar1, bar2 ) )  I want to obtain `bar1' and `bar2' given
tablename `foo'.  DatabaseMetaData.getPrimaryKeys looks like the right function to use, but it returns `foo_pk' in
COLUMN_NAMEfor all rows.  Am I misinterpreting the JDBC specs?  What SELECT query should I use to get the primary key
columns?
