so that only one signal number is used not three.  Flags in shared
memory tell the reason(s) for the current signal.  This method is
extensible to handle more signal reasons without chewing up even more
signal numbers, but the immediate reason is to keep pg_pwd reloads
separate from SIGHUP processing in the postmaster.
Also clean up some problems in the postmaster with delayed response to
checkpoint status changes --- basically, it wouldn't schedule a checkpoint
if it wasn't getting connection requests on a regular basis.

make it clearer that d was the argument to the format operator.

- Fix handling of {data/schema}-only restores when using a full
  backup file; prior version was restoring schema in data-only
  restores. Added enum to make code easier to understand.

his patch.

about.

particularly in the CREATE TYPE reference page.  Fix some other errors
in the CREATE TYPE page, too.

2) Remove some no longer valid comments.
3) Fix an option dialog setting bug.
4) Fix ODBCVER handling errors.

analysis.  This keeps stored rules from prematurely absorbing default
information, which is necessary for ALTER TABLE SET DEFAULT to work
unsurprisingly with rules.  See pgsql-bugs discussion 24-Oct-01.

postmaster children before client auth step.  Postmaster now rereads
pg_pwd on receipt of SIGHUP, the same way that pg_hba.conf is handled.
No cycles need be expended to validate password cache validity during
connection startup.

recreated since the start of our transaction, our first reference to it
errored out because we'd try to reuse our old relcache entry for it.
Do this by accepting SI inval messages just before relcache search in
heap_openr, so that dead relcache entries will be flushed before we
search.  Also, break heap_open/openr into two pairs of routines,
relation_open(r) and heap_open(r).  The relation_open routines make
no tests on relkind and so can be used to open anything that has a
pg_class entry.  The heap_open routines are wrappers that add a relkind
test to preserve their established behavior.  Use the relation_open
routines in several places that had various kluge solutions for opening
rels that might be either heap or index rels.

Also, remove the old 'heap stats' code that's been superseded by Jan's
stats collector, and clean up some inconsistencies in error reporting
between the different types of ALTER TABLE.

Tom Yackel.  Note: in the case of encrypted passwords this is no
restriction, since the string we are interested in is the MD5 hash.
