persistent_conn was left dangling after a disconnect in the
unnamed connection case, causing a subsequent disconnect to
crash the backend.

--with-openssl options. This creates too much risk to pick up the wrong
directory accidentally (for example when there are lib64 directories), and
does not really help much with contemporary installation layouts.

Ward's report that it can still happen in RC2 forces me to realize that
this is not a can't-happen condition after all, and that the compaction
code had better cope rather than panicking.

Vars created to fill subplan args lists. This is an ancient error, going
back at least to 7.0, but is more easily triggered in 7.4 than before
because we no longer compare varlevelsup when deciding whether a Param
slot can be re-used. Fixes bug reported by Klint Gore.

tree for CYCLE option; don't assume zeros are invalid values for sequence
fields other than increment_by; don't reset cache_value when not told to;
simplify code for testing whether to apply defaults.

back --infodir, which several automatic build environments expect to exist.
Add --without-docdir to prevent installation of documentation, which is
helpful for things like RPM that have their own method of installing
documentation.

large objects. Dump all these in pg_dump; also add code to pg_dump
user-defined conversions. Make psql's large object code rely on
the backend for inserting/deleting LOB comments, instead of trying to
hack pg_description directly. Documentation and regression tests added.

This first part of the background writer does no syncing at all.
It's only purpose is to keep the LRU heads clean so that regular
backends seldom to never have to call write().

regression tests for this, too.
