Re: Increasing code-coverage of 'make check'

I think increasing coverage is a good thing.  But psql help?  *shrug*
backend code is far more interesting and useful.

Another thing to keep in mind is that there are some corner cases that
are interesting to test that might not necessarily show up in a coverage
chart -- for example how stuff behaves in the face of concurrent
processes, or when various counters wrap around.

Peter Eisentraut has set up a Jenkins instance that publishes coverage
info.
http://pgci.eisentraut.org/jenkins/job/postgresql_master_coverage/Coverage/
(I think he only has it running "make check"; doing the isolation tests
probably raises percentages a bit).
