Обсуждение: SET database TO ...?

Hi,

Suppose, one server/postmaster is running several databases. Is there something
like "SET database TO whatever" (and I mean *database* not schema). I need this
to ensure that a script runs only against db for which it was desinged.

Thanks

[postgres@smadev ~]% psql
Welcome to psql 7.3.4, 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
 

dynacom=# \c bab
You are now connected to database bab.
bab=# 
bab=# 
bab=# \c dynacom
You are now connected to database dynacom.
dynacom=# \q

You can use PG* environment variables if you wish to write seperate script
for each databases.

I'm actually looking for a way to set database from a *script*, not psql
console, if this is possible (similar to "SET search_path TO whatever;").

Any ideas? Thanks

If the script is being fed to psql, it can use \c ...
