Обсуждение: character limit on db names in PGSQL or what?

had a db named: prysm_shreveport
with one table named 'shreveport'


came back later and did:
createdb prysm_shreveport2
psql -e prysm_shreveport2 < shreveport2.sql --> which creates table
                                                'shreveport2'

then:
psql prysm_shreveport2

which to my suprise had 2 tables! shreveport, and shreveport2


So I started with:
createdb prysm_shreveport3

psql prysm_shreveport3
suprise, suprise, it already has two tables in it, shreveoprt, and
shreveport2

so what I can tell

createdb prysm_shreveport3 (does in deed create a new database, that I can
see by doing: psql then \l to list all dbs)

destroydb prysm_shreveport3 will actually delete the database.

but to do something like
psql prysm_shreveport3 doesn't actually connect me to that database
it actually connects me to prysm_shreveport even though my command line
looks like this in psql: prysm_shreveport3=>

even if there is no database listed as prysm_shreveport2
I can do: psql prysm_shreveort2
and it looks and acts as though I'm connected to prysm_shreveport2 when
actually it's prysm_shreveport that I'm connected to.


I'm thinking an error message somewhere along the line or something would
have been nice, and fortunately no data was lost in this process, very
easily could have been however.

currently running postgres 6.3.x I've got 6.4.x running at home, I was
going to try it there too, just to see what happens. I just thought this
was strange.

Seems to be fixed w/ 6.4.2:

$ createdb createdb prysm_shreveport
$ createdb createdb prysm_shreveport2
$ psql prysm_shreveport
