Re: [SQL] SQL-Query 2 get primary key

You may query pg_indexes as in:

select * from pg_indexes where tablename = 'test';

tablename|indexname|indexdef
---------+---------+-----------------------------------------------------------------------

test |test_pkey|CREATE UNIQUE INDEX "test_pkey" ON "test" USING btree
("id" "int4_ops")
(1 row)
