path into executables and shared libraries (-rpath or -R for most). Can be
disabled with --disable-rpath, since some binary packaging standards do not
like this option.
on pghackers. Arrange for the sort ordering of general INET values
to be network part as major sort key, host part as minor sort key.
I did not force an initdb for this change, but anyone who's running
indexes on general INET values may need to recreate those indexes.
ExecutorRun. This allows LIMIT to work in a view. Also, LIMIT in a
cursor declaration will behave in a reasonable fashion, whereas before
it was overridden by the FETCH count.
MULTIBYTE support is not compiled (you just can't set them to anything
but SQL_ASCII). This should reduce interoperability problems between
MB-enabled clients and non-MB-enabled servers.
support is not present. This allows a non-MB server to load a pg_dumpall
script produced by an MB-enabled server, so long as only ASCII encoding
was used.
the -l options. (This was not the case when using the OpenSSL or Kerberos
options.) Also make sure that shared library links get to see all the -L
options. Get Kerberos 5 support to compile on Redhat 7.0. Add OpenSSL and
-lsocket (if used/found) to libpq link.
I modified the current ODBC driver for
* referential integrity error reporting,
* SELECT in transactions and
* disabling autocommit.
I tested these changes with Borland C++ Builder -> ODBCExpress ->
WinODBC driver (DLL) -> Postgres 7.0beta1 and Borland C++ Builder -> BDE ->
WinODBC driver (DLL) -> Postgres 7.0beta1. The patch is based on snapshot of
22th April (I don't think that someone has modified it since that: Byron
hasn't gave any sign of living for about a month and I didn't find any
comments about the ODBC driver on the list).
'AbortTransaction and not in in-progress state' when client disconnects
just after an error. Notice seems pretty harmless, so I'm not going
to worry about back-patching this into 7.0.* ...
as full as possible, seems better to use a tuple size around BLCKSZ/4
so that less space is wasted when a LO tuple is updated. Also, this
lets us use a logical page size that's an exact power of two, avoiding
partial-page writes when client is sending us stuff in power-of-2
buffer chunks.
kibitzing from Tom Lane. Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'. This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines. LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.
INITDB forced!
