add check for libz compression library for pg_dump

Special handling of TOAST relations during VACUUM. TOAST relations
are vacuumed while the lock on the master table is still active.
The ANALYZE flag doesn't propagate to their vacuuming because the
toaster access routines allways use index access ignoring stats, so
why compute them at all.

Protection of TOAST relations against normal INSERT/UPDATE/DELETE
while offering SELECT for debugging purposes.

PostgreSQL-7.0.2 run on Linux for the Intel-IA64 architecture. It also
fixes a bug in the configure scripts that caused configure to fail on
the fcntl(F_SETLK) test.

This fix triggered a bug in the fcntl(F_SETLK) code of the Linux
kernel when used on unix domain sockets resulting in postmaster to
segfault immediately after startup. There is a fix available and
included in the kernel that will be on SuSE Linux 7.0, but kernels <=
2.2.16 still have this bug.

and SELECT ... INTO ... too.

Automatically create toast table at CREATE TABLE if new table
has toastable attributes.

but can still use the pg_shadow password. (You just leave off the
password field in the secondary file.)

Doesn't anyone remember how to program a binary search??

from Paul McGarry.

Don't go through pg_exec_query_dest(), but directly to the execution
routines.  Also, extend parameter lists so that there's no need to
change the global setting of allowSystemTableMods, a hack that was
certain to cause trouble in the event of any error.

    WARNING: This is actually broken - we have self-deadlocks

parsing to not clobber the optarg string -- so that we can bring
SetOptsFile() up to speed.

COPYs of pg_shadow and pg_group.

It also turns out that pg_dumpall was all but broken for multiple servers
running at non-standard port numbers. You might get the users and groups
from one server and the databases from another. Fixed that.

A little user interface and code cleanup along with that. This also takes
care of the portability bug discussed in "[BUGS] pg_dumpall" in March 2000.

 And:

 Note, Bruce I found in the contrib tree any files that we forget
remove during contrib cleaning. Please remove these files:

contrib/lo/test.sql
contrib/pg_dumplo/Makefile.out
contrib/pgbench/pgbench_jis.doc
contrib/spi/new_example.example
contrib/spi/README.MAX

Thanks.
