for switch over to configure

#if defined(aix)
#define TERMIOS_H_LOCATION <termios.h>
#else
#define TERMIOS_H_LOCATION <sys/termios.h>
#endif

libpq/fe-exec.c modified so that location of termios.h is determined
by whether HAVE_TERMIOS_H is defined or not, in preparation for switch
to configure

to be committed...

Cleaned out alot of the #define that can be auto-detect'd by
configure from config.h...

the ports section of Makefile.global as a result.

Right now, it only auto-detects FreeBSD, and the rest still get set
to UNDEFINED, but its a step in the right direction, no?

Autoconf bin/psql/Makefile

readline and associated libraries...

configure, thereby reducing the ports dependencies in it :)

in v6.0 does...

configure is auto-finding

Mv Makefile.in to GNUmakefile.in and reflect the change in the
configure script

it still needs lots of work, but, hey, at least this way there are more
ppl working off the same "Source"...

Tcl arrays support. Here are the correct values to be defined in config.h
and pgtclCmds.c.

It should be completely harmless.

The first patch changes the behavior of aclcheck for groups. Currently an user
can access a table only if he has the required permission for ALL the groups
defined for that table. With my patch he can access a table if he has the
permission for ONE of the groups, which seems to me a more useful thing.
If you think this should be the correct behavior of the acl group check feel
free to remove the #ifdef, if not please add a commented line to config.h.

which probably isn't needed, since we are going to take off -Werror
anyway, right?

(but I didn't test FUNC OP PARAM and PARAM OP FUNC - no time)

2. IndexScanableOperand now uses match_indexkey_operand
instead of equal_indexkey_var (if we have some index on attribute X
then we shouldn't use it for 'where some_func(X) OP CONST').

ExecInitIndexScan now works with operands of Param type and
(!!!) postquel_execute() now substitutes param values
before calling postquel_start().

/usr/include/limits.h (which quiets the costsize.c warnings)...under
FreeBSD, /usr/include/limits.h *includes* machine/limits.h, while under
Solaris, there is no such things as /usr/include/machine...

Problem with Solaris pointed out by Mark Wahl

Invalidate vacuum relation cache to use new row counts from vacuum.

1. New flag - BM_JUST_DIRTIED - added for BufferDesc;
2. All data "dirtiers" (WriteBuffer and WriteNoReleaseBuffer)
   set this flag (and BM_DIRTY too);
3. All data "flushers" (FlushBuffer, BufferSync and BufferReplace)
   turn this flag off just before calling smgr[blind]write/smgrflush
   and check this flag after flushing buffer: if it turned ON then
   BM_DIRTY will stay ON.

losing data changes.
