sql.py: table_pkey_col(): For PostgreSQL DBs, use pg_catalog via index_cols() and table_pkey_index(), in order to use the search_path to look up the table. This fixes a bug where the pkey would be selected from information_schema.table_constraints in random order, and this order sometimes returned the corresponding table in the public schema but sometimes in other schemas, such as VegBank. This became a problem now that VegBIEN has a place table, which conflicts with VegBank's place table. (Most other VegBank tables that are mapped to have been renamed in VegBIEN.)
