Обсуждение: pgdump
Hello,
if I do a database dump via pg_dump also PostgreSQL internal tables
named pga_* are stored in the dump. However if I drop a database and
create it via "create database <name>" those tables are created
automatically. Restoring the old content of the database using
cat <name>.dump | psql <name>
leads to warning messages caused by the existence of the pga_*
tables. This is really annoing. I checked all pg_dump options
if this could be avoided, but didn't found any.
I wonder if I should write a little script to remove the pga_*
stuff from the dump to get a warning-free restore.
Is there any usual solution for this problem?
Kind regards
Andreas.

This is what I thought, but the following script:
#!/bin/sh
echo "create database test ;" | psql
pg_dump -n -c test
creates the output:
\connect - postgres
DROP TABLE pga_queries;
CREATE TABLE pga_queries (

That's really annoying.

Hmm, yes I use also the Debian-Packages from woody.

Have you used pgaccess on template1 database. I assume that it creates these tables in any db it sees. After that 'create database' will make these tables as you describe. Remove them from template1 should fix this.

Thanks, this works.
Kind regards

That would create the pga_* tables in there, which would then propagate to all newly crreated dbs. Pgaccess makes these files behind the users back. It might be reasonable for it _not_ to create them in template1, if possible, without prompting the user, at least. I'll ask Constantin about it. The workaround is to go into template1 with psql and drop the pga_* tables, then never use pgaccess to look in there. Ross -- Ross J.

Yes, this was the reason.

That's a nice idea!
This reminds me to a further issue on this topic:
By accident I filed a dump not to the intended database, but to
template1. This is not hard to do because I wrote a script like
#!/bin/sh
MYDB=<some_function>
cat dumpfile | psql $MYDB
unfortunately I hadn't checked whether $MYDB could be "" :-(.
So I filled my template1 database with a lot of rubish.
Nice exercise to remove this rubish which introduced me a little bit
deeper into PostgreSQL internal tables :). Hope that I got rid off
all this stuff.
So the idea is to make it a little bit harder to put something into
template1 or, alternatively serve a method which helps out such kind
of situation.
.... just an idea ...
> The workaround is to go into template1 with psql and drop the pga_*

Or just to call my script which removes all tables and sequences
which are not created by user postgres :).
Kind regards
Andreas.
Hi there! I need to import a CVS file generated by SQL Server into PostgreSQL but I could not no ready utility to do this on postgresql.org. A command line utility like msqlimport would be perfect, as I need to use this on cron jobs. Anyone there can pelase pointe to such utility? []s, Fernando Lozano

Someone said this command only accepts TAB delimited files, with no string delimiter. Is it possible to change these settings? []s, Fernando Lozano

Have a look at:
http://www.postgresql.org/docs/user/sql-copy.htm
But, yes, you can change the delimiter using the 'DELIMITERS' clause.

I have some perl scripts which I use to do this - you are welcome to
them.

Use a 9.3+ version of pg_dump. A version of pg_dump is backwards compatible so it can work on its version to Postgres versions going back to 7.2, I believe. That does not work the other way around as you found above. pgAdmin3 is picking up a 9.1.3 version of pg_dump and trying to use it to dump a 9.3 version of Postgres. So you will need to find the 9.3 version of pg_dump and use that. > > Advanced thanks, -- Adrian Klaver adrian.klaver@aklaver.com

To add to what Adrian says, you tell pgAdmin which pg_dump (and other Postgres client programs) to use under File -> Options -> Browser -> Binary paths, in the "PG bin path" field (this is on PgAdmin III 1.20).
