Обсуждение: parse errors when connecting to remote host

Hi everybody

When connecting to a remote host I get some strange parse errors. Here
the output from the console:

$ psql -h hostname -U username
Password:
ERROR:  parser: parse error at or near "."
Welcome to psql 7.3.2, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help on internal slash commands
       \g or terminate with semicolon to execute query
       \q to quit

postgr=> \d
ERROR:  parser: parse error at or near "."
postgr=> \l
ERROR:  parser: parse error at or near "("

Other backslash-commands like \x \q \? \r are working as expected.

my version: 7.3.2
version on target host: 7.2.0

Can anybody give some hints what's wrong?

Thanks in advance
Conni

Version 7.3 psql using pre-7.3 database? You get similar errors with 7.2
psql on 7.0 database (though \d works, just not \df).

Use a version of 'psql' that matches the version on the server
side--mixing versions can cause problems due to changes in the system
catalog format.

You've just pointed out the problem. I'm guessing it's schema-related. They
were added in 7.3 and so it's probably sending queries like:
  SELECT * FROM pg_catalog.footable...

Looks like you'll either want to ssh to the remote host and use its psql, or
install both versions of the client.
