I'm thinking of removing the datatype "filename", which is a fixed-size
array of 256 characters with no support functions other than input and
output converters. Apparently it was once used in the system tables,
but it is so no longer AFAICT. Since it's fixed-length, it cannot be
made TOASTable, which makes it substantially inferior to type "text"
for any purpose that I can think of.
Anyone using this type?
