The following select keeps returning "(0 rows)".
LIKE doesn't consider [2-5] to be a range, but rather the literal
characters '[2-5]'. If you're looking for regex, take a look at the
POSIX regex operator ~
http://www.postgresql.org/docs/current/interactive/functions-
matching.html#FUNCTIONS-POSIX-REGEXP
See if something like file_name ~ 'abc.*def.*\.200[2-5]'
select '2003' ~ '200[2-5]' as "yup", '2006' ~ '200[2-5]' as "nope";
yup | nope
-----+------
t | f
