  1. Fixup some appendStringInfo and appendPQExpBuffer calls

  1. Use appendStringInfoString and appendPQExpBufferStr where possible

    Hi hackers

In(/src/bin/scripts/reindexdb.c; /src/backend/access/rmgrdesc/dbasedesc.c; /src/pl/plpython/plpy_elog.c)

I found some more places that should use appendPQExrBufferStr instead of appendPQExpBuffer.

Here is the patch.

Seems like a good idea.  Please add it to the next commitfest.

Thanks for your response, combined them as a single patchset now.

I had a look over the three patches.  All the changes look fine.
Thanks for working on it.

After a bit of grep work, I found about 6 times more calls that could
be improved.  These involved searching for appendStringInfo calls that
could become appendStringInfoString calls and also appendPQExpBuffer
that could be converted to appendPQExpBufferStr.

I didn't really go hunting for any other calls that append a 1 char
string that don't use the Char variant of the function. So perhaps
there's more of those to be found.

I've attached the patch I ended up with. I plan on pushing this in the
next few days.
