Errors found by static analysis tool

Hi,

I'm sending this mail again, because the first two attempts don't seem
to be successful (sorry if it's duplicate). Trying without the
attachments, they can be found at links below.

psql-odbc-09.00.0200 has been scanned using Coverity static analysis
tool, which discovered several more or less severe problems [1]. Please
note, that there can be some false positives, but many of them are real
issues.

A patch [2] with some obvious fixes and the error report itself are
attached.

Cheers,

Honza
