Hello,

I found below situation weird, it seems to me a bug.

backend=> select * from valid_addr;zip_code |      city_name       | state_abrev

backend=> select * from valid_addr where state_abrev=upper('pr');zip_code | city_name | state_abrev
----------+-----------+-------------
(0 rows)

while "select * from valid_addr where state_abrev='PR';" produces following
output
zip_code |     city_name     | state_abrev
