About pg_encoding. There is currently no way to tell whether an encoding
exists. Normally you would put this kind of thing into a system table,
but doing that is a bit tricky with the encodings. I would like to see
pg_encoding go, so let's hear what information people need and give them a
direct way to access it.
I currently use pg_encoding in Debian's automatic upgrade script to extract the existing default encoding from pg_database, thus:
$ psql -q -t -d template1 -c "select encoding from pg_database where datname = 'template1'" 0
and then I use it to translate that number into an encoding name that can be fed to initdb.
However, on looking at this, I can see that I don't need it, since I can just as well do
$ psql -l | grep template1 | awk '{print $5}' SQL_ASCII
so as to achieve the same result with only a single command.
Therefore, you don't need to keep pg_encoding for my (the Debian package's) sake.
psql -l | awk '/template1/ { print $5 }'
Anyway, it looks like maybe we can get rid of pg_id and pg_encoding after all.
