What would be the SQL to find data of this nature? My column can only
have alphanumeric data, and the only symbols allowed are "-" and "_",
so I tried this regexp query:
select id, t_code

If you're including - in a range as a character, doesn't it have to
go first?
Try this:
WHERE t_code ~ $re$[^-A-Za-z1-9_]$re$

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
