not TRUE. Otherwise we break pl call handler functions. fmgr_oldstyle
will take care of making sure the semantics are the same for C functions.
Clean up some slightly grotty coding in 7.0 pg_class reading, also.
when we need to move to a new page; as long as we can insert the new
tuple on the same page as before, we only need LockBuffer and not the
expensive stuff. Also, twiddle bufmgr interfaces to avoid redundant
lseeks in RelationGetBufferForTuple and BufferAlloc. Successive inserts
now require one lseek per page added, rather than one per tuple with
several additional ones at each page boundary as happened before.
Lock contention when multiple backends are inserting in same table
is also greatly reduced.
- Fix view dumping SQL for V7.0
- Fix bug when getting view oid with long view names
- Treat SEQUENCE SET TOC entries as data entries rather than schema
entries.
- Make allowance for data entries that did not have a data dumper
routine (eg. SEQUENCE SET)
not being consulted anywhere, so remove it and remove the _mdnblocks()
calls that were used to set it. Change smgrextend interface to pass in
the target block number (ie, current file length) --- the caller always
knows this already, having already done smgrnblocks(), so it's silly to
do it over again inside mdextend. Net result: extension of a file now
takes one lseek(SEEK_END) and a write(), not three lseeks and a write.
a PostgreSQL user-defined function. The Metaphone system is a method of
matching similar sounding names (or any words) to the same code.
Metaphone was invented by Lawrence Philips as an improvement to the popular
name-hashing routine, Soundex.
This metaphone code is from Michael Kuhn, and is detailed at

P.S. in Connection.java if encoding=="WIN" then dbEncoding is set to
"Cp1252".
What if it's Cyrillic "WIN"? Than it should be "Cp1251". Is there any
way to fix that without making different "WIN" encodings in
PostgreSQL?

in referencing and referenced columns of an fk constraint
aren't comparable using '=' at constraint definition time
rather than insert/update time.

enables pltcl unknown support.
Also it adds substituting of tclsh with tclsh that was by configure in
pltcl_*mod scripts. For example, On freebsd, tclsh can be called
tclsh8.2 or
tclsh8.3 depending on installed version of Tcl.
After patching files
src/pl/tcl/modules/pltcl_listmod
src/pl/tcl/modules/pltcl_loadmod
src/pl/tcl/modules/pltcl_delmod
must be renamed(copied,repocopied) to
src/pl/tcl/modules/pltcl_listmod.in
src/pl/tcl/modules/pltcl_loadmod.in
src/pl/tcl/modules/pltcl_delmod.in

still looking at the best way to integrate Tom Vijlbrief's fixes
(insofar as they're still needed); would 7.2 be a suitable time for
incompatible API changes?

Changes:
(*) Introduced bool, true, false (replacing some int, 1, 0)
(*) Made some member functions const
(*) Documented GetIsNull()
(*) Marked DisplayTuples() and PrintTuples() as obsolescent; fixed possible
portability problem (assumed that NULL pointer equals all-zero bit pattern)
(*) PrintTuples(): renamed width parameter to fillAlign to conform with other
usage; fixed memory leak and compile issue w.r.t. field separator (should
also slightly improve performance)
(*) Fixed some minor compilation issues
(*) Moved "using namespace std;" out of headers, where they didn't belong; used
new (temporary) preprocessor macro PGSTD to do this
(*) Made ToString() static, removed unneeded memset(), made buffer size adapt
to sizeof(int)
(*) Made some constructors explicit
(*) Changed some const std::string & parameters to plain std::string
(*) Marked PgCursor::Cursor(std::string) as obsolescent (setter with same name
as getter--bad style)
(*) Renamed some paramaters previously named "string"
(*) Introduced size_type typedef for number of tuples in result set
(*) PgTransaction now supports re-opening after closing, and aborts if not
explicitly committed prior to destruction

collected by ANALYZE. Also, add some modest amount of intelligence to
guesses that are used for varlena columns in the absence of any ANALYZE
statistics. The 'width' reported by EXPLAIN is finally something less
than totally bogus for varlena columns ... and, in consequence, hashjoin
estimating should be a little better ...
to their children, leading to misbehavior if they had any children that paid
attention to chgParam (most plan node types don't). Append's bug has been
there a long time, but nobody had noticed because it used to be difficult
to create a query where an Append would be used below the top level of a
plan; so there were never any parameters getting passed down. SubqueryScan
is new in 7.1 ... and I'd modeled its behavior on Append :-(
