Sorry if this was discussed and I missed it, but I think this is a bad idea. There's already an option to control this. More important, there's no option to force the rc files to be used, so if -g disables them you'd be stuck with that.

I agree that the rc files are a danger when scripting, but if we want to do something about that then it needs to be consistent for ALL non-interactive use.

I don't see any problem to load rc files - but should I do it by default? I prefer

1. default - don't read rc
2. possible long option for forcing load rc for -c and -g
3. possible long option for forcing load any file as rc for -c and -g


​--psqlrc​
 
​; read the standard rc files​
--no-psqlrc ; do not read the standard rc files

It belongs in a separate patch, though.

In this patch -g should disable the reading of the standard rc files.

Yet another option could be added that allows the user to point to a different set of rc files.  Its presence should not cause the include/exclude behavior to change.  That way you can setup a psql wrapper function or alias that uses a different ​rc file while still having control over whether it is included or excluded.  The problem here is exploding the logic in order to deal with both a system and a user rc file.

This would be yet another patch.
