BUG #2177: (minor:) pgsql: Trailing semicolon on \d treated as argument

The following bug has been logged online:

Bug reference:      2177
Logged by:          Giles Morant
Email address:      giles.pg@chaletpomme.com
PostgreSQL version: 8.1.1
Operating system:   Linux (Gentoo)
Description:        (minor:) pgsql: Trailing semicolon on \d treated as
argument
Details:

When describing tables/view/indexes using \d, a semi-colon is optional:
e.g.  \d users;
or:   \d users
Both give the same (correct) results.

However, if there is a space between "users" and the semi-colon, the
semi-colon is then treated as an argument and this occurs:
   \d users ;
   <cut lots of table info>
   \d: extra argument ";" ignored

The semi-colon should be ignored silently, in my view- "SELECT 1+2 ;" for
example doesn't raise an alert.

I searched the mailing lists to find a previous report of this very minor
bug; the closest I found was some discussion in 2001 of stripping
semi-colons from the end of such strings but the discussion seemed to stop
with no resolution.

We can't just throw away semicolons, e.g.:

    \test=> \f ;
    Field separator is ";".

The current behavior seems pretty good.  It doesn't seem worth
improving.

I agree we cannot just throw the semi-colon away, but the action of
"\d" to assume the semi-colon is an argument and thus invalid is in my
view wrong.

I didn't say what we are doing is right, I said fixing it would not be
worth it.  If you want, submit a patch and we can decide.

Remember, \d can throw it away, but other backslash commands can not.
