[Squirrel-sql-users] <UnknownType (2, 001)> in all of the PostgreSQL information_schema system views

[info <in...@dr...>]

Is there a reason for Squirrel to show <UnknownType (2,001)> for all 
values of all columns in PostgreSQL information schema system views? 
There is no such issue in user catalogs/schemas or in pg_catalog.
I tried with their latest 42.7.13 driver as well as with some older 
9.4.1212 driver that I have been using for the past several years.
Is this something that the PostgreSQL development team should be 
correctly exposing/mapping in their driver for the applications to pick up?
