Thread: naming a primary key possible?
Is it possible to name a primary key (composite) primary key rather than have pg default to table_name_pkey?? I tried something like primary key pkey_table_short_form_name (a,b,c) but it didnt' work.

This definitely works.. Thanks.. Indexes: "trd_pkey" PRIMARY KEY, btree (trd_pkey)
