This worked, thank you so much; I'm still stuck in Oracle mode. Thank you to everyone that responded.
Thanks,

Somewhat confusingly, '_' is the single-character wildcard for SQL's LIKE operation:
xof=# SELECT 'A' LIKE '_';
?column?
----------
t
(1 row)
You can escape it to search for it literally:
xof=# SELECT '_' LIKE '\_';
?column?
----------
t
(1 row)
xof=# SELECT 'A' LIKE '\_';
?column?
----------
f
(1 row)
