Tom Lane 3e23b68dac Support varlena fields with single-byte headers and unaligned storage. 
This commit breaks any code that assumes that the mere act of forming a tuple
(without writing it to disk) does not "toast" any fields.  While all available
regression tests pass, I'm not totally sure that we've fixed every nook and
cranny, especially in contrib.

Tom Lane b3005276eb Decouple the values of TOAST_TUPLE_THRESHOLD and TOAST_MAX_CHUNK_SIZE. 
Add the latter to the values checked in pg_control, since it can't be changed
without invalidating toast table content.  This commit in itself shouldn't
change any behavior, but it lays some necessary groundwork for experimentation
with these toast-control numbers.

Note: while TOAST_TUPLE_THRESHOLD can now be changed without initdb, some
thought still needs to be given to needs_toast_table() in toasting.c before
unleashing random changes.

Bruce Momjian 17285959c1 Add URL for: 
* Improve speed with indexes

  For large table adjustments during VACUUM FULL, it is faster to cluster
  or reindex rather than update the index.  Also, index updates can bloat
  the index.

Magnus Hagander 96b171903d Make ECPG regression tests use native threading instead of pthreads, now that 
ecpglib supports it.
Change configure (patch from Bruce) and msvc build system to no longer require
 pthreads on win32, since all parts of postgresql can be thread-safe using the
 native platform functions.
