Hi,
1.Select server
2.Select database
3.select schema
4.select table with primary key which contains character varying.field
5.look in SQL pane line for the primary key definition
If your selected server is PostgreSQL 9.1, primary key looks like:
CONSTRAINT edi_razmena_pkey PRIMARY KEY (godina COLLATE
pg_catalog."default", razmena_id COLLATE pg_catalog."default", kupac
COLLATE pg_catalog."default")
6.If you apply patch, primary key looks like:
CONSTRAINT edi_razmena_pkey PRIMARY KEY (godina, razmena_id, kupac)
