Thread: BUG #3363: Unable to load a plugin/library using -c switch to the psql

The following bug has been logged online:

Bug reference:      3363
Logged by:          Gurjeet Singh
Email address:      singh.gurjeet@gmail.com
PostgreSQL version: 8.3devel
Operating system:   Windows
Description:        Unable to load a plugin/library using -c switch to the
psql
Details:

The following command fails:

psql postgres test -X -c "load '$libdir/plugins/index_adviser.dll';"

    Here, 'test' user (non-superuser) is trying to connect to 'postgres'
database, and wishes to load a plugin as the first step.

    But if the same 'load' command is fired by the same user after log-in
using psql, then the command succeeds.

postgres=> load '$libdir/plugins/index_adviser.dll';
NOTICE:  IND ADV: Loaded; PID: 1164
LOAD
postgres=>

I've not done what you're doing, so this is just a suggestion.  I'm
not sure about the Windows shell, but the bash shell will convert
$libdir before handing it off to psql.  Is it possible that $libdir
has a different meaning in psql than it does to the shell?

Define "fails".  I get complaints about the arguments being out of
order, which they are ...

If you think that -c means "run this command and then go into normal
interactive mode", you're wrong anyway.

I am actually using MinGW, so no I am not using Windows shell but a bash
shell compiled for Windows.

Yes, it was actually the bash, interpreting the $ symbol in a special way,
hence the problem. I tried the following (notice \$ , escaping $ sign ) and
now it works...

$ psql postgres test -X -c "load '\$libdir/plugins/index_adviser.dll';"
NOTICE:  IND ADV: Loaded; PID: 4968
LOAD

Had I been using the Windows shell, I wouldn't have faced this problem :)

Thanks for the pointer....

not a bug

No, I do not wish to do that (I use the .psqlrc for that purpose); this is
the first command in a sequence of commands that I want psql to execute and
exit.
