SQLSmith finds many internal program errors (`elog`, code `XX000`).
Normally these errors shouldn't be triggered by user actions and
indicate a bug in the program (like `variable not found in subplan
targetlist`). We don't have a capacity to fix all of them currently,
especially since some of them seem to be the upstream ones. This commit
adds logging for these errors so that we at least can study the current
situation.
Fix missing alignment handling, and also buffer size problems. We were
not properly reporting the failures in the compression_algo tests, so
didn't notice these problems. Add part of tests from "vector text
predicates" PR to improve coverage.
This patch contains two changes to the Sanitizer checks:
(1) All logfiles of the Sanitizer will be uploaded to the
CI database.
(2) The Sanitizer checks are executed on every PR.
