[SQL] arrays in PostgreSQL

AICR, it is impossible. In addition, it's not suggested using arrays at
all: the array based logic is foreign from SQL solutions. In fact
PostgreSQL doesn't have a good array support. My friend who built our
logic data model, said that the pg_group table is a bad idea in
PostgreSQL, he would have created a new table to store relations between
groups and users. I don't think it can be modified after such a long time.
