Yeah, this seems to be a long-standing misbehavior. I get the same
results as far back as PG 7.0 (the oldest version I have running):
play=> select * from teste;serie | aula
-------+----------------------------------------------------- 1 | {{"004","009"},{"009",""},{"",""},{"001","002"}}
1 | {{"004","009"},{"009","001"},{"",""},{"001","002"}}
(2 rows)
On the other hand, the last time I fixed what seemed an obvious bug in
the array-value parser, I got flak for it. Anyone want to defend the
present behavior?
