Re: [PATCH] Filter error log statements by sqlstate

I had a quick look over the patch (Not compiled though). Here are few
comments on the changes:

1. Documentation is missing and thus becomes difficult to understand what
exactly you are trying to do. Or in other words, user will be uncertain about
using it more efficiently.
2. Some more comments required. At each new function and specifically at
get_sqlstate_error_level().
3. Please add test-case if possible.
4. Some code part does not comply with PostgreSQL indentation style. (Can be
ignored as it will pass through pg_indent, but better fix it).
5. You have used ""XX000:warning," string to get maximum possible length of
the valid sqlstate:level identifier. It's perfect, but small explanation about
that will be good there. Also in future if we have any other error level which
exceeds this, we need changes here too. Right ?

I will look into this further. But please have your attention on above points.
