would close and then re-open rel being truncated. Depending on the
luck of the draw, the re-opened relcache entry might or might not be
at the same physical location as before. Unfortunately, if it wasn't
then heap_truncate would crash and burn, because it still had a pointer
at the old location. Fix is to open and then close rel in
RelationTruncateIndexes, so that rel's refcount never goes to zero
until heap_truncate is done.
and the fmgr redesign.
It makes the homebrewn dl*() functions for more recent Versions of AIX
obsolete
by using the system dl*() functions instead.
It also fixes the expected file for the horology regression test.
Please regenerate configure from configure.in, I don't have the
environment/time.

(Don't forget that an alias is required.) Views reimplemented as expanding
to subselect-in-FROM. Grouping, aggregates, DISTINCT in views actually
work now (he says optimistically). No UNION support in subselects/views
yet, but I have some ideas about that. Rule-related permissions checking
moved out of rewriter and into executor.
INITDB REQUIRED!
Update the installation instructions (formerly misnamed "FAQ"), add configure
checks for some headers rather than having users copy stubs manually (ugh!).
Use Autoconf check for exe extension. This also avoids inheriting the value
of $(X) from the environment.
illegal call to pg_mbclipen() that is for backend only. However I
have not remove the entire part of the problem, rather mark it with
#ifdef MULTIBYTE_NOTUSED since we should come back with a long range
solution someday.
add --without-tk option to disable Tk. We don't need the AC_PATH_XTRA
test because tkConfig.sh already contains all the information about how to
compile and link with X. Also make sure that libpq is up to date for
libpgtcl. Remove executable bits from pgaccess.sh, but add it to pgaccess.
complaints about ungrouped variables. This is for consistency with
behavior elsewhere, notably the fact that the relname is reported as
an alias in these same complaints. Also, it'll work with subselect-
in-FROM where old code didn't.
- rename ichar() to chr() (discussed with Tom)
- add docs for oracle compatible routines:
btrim()
ascii()
chr()
repeat()
- fix bug with timezone in to_char()
- all to_char() variants return NULL instead textin("")
if it's needful.
The contrib/odbc is without changes and contains same routines as main
tree ... because I not sure how plans are Thomas with this :-)

This effectively one line patch should fix the fact that
foreign key definitions in create table were erroring if
a primary key was defined. I was using the columns
list to get the columns of the table for comparison, but
it got reused as a temporary list inside the primary key
stuff.

query representation. Note that GEQO_RELS setting is now interpreted
as the number of top-level items in the FROM list, not necessarily the
number of relations in the query. This seems appropriate since we are
only doing join-path searching over the top-level items.
There is still no effective difference but it will kick in once setuid
functions exist (not included here). Make old getpgusername() alias for
current_user.
