Few cleanups and couple of new things:
- add SHA2 algorithm to older OpenSSL
- add BIGNUM math to have public-key cryptography work on non-OpenSSL
build.
- gen_random_bytes() function
The status of SHA2 algoritms and public-key encryption can now be
changed to 'always available.'
That makes pgcrypto functionally complete and unless there will be new
editions of AES, SHA2 or OpenPGP standards, there is no major changes
planned.
fe-auth.c:573: warning: passing argument 1 of 'free' discards qualifiers
from pointer target type
pg_krb5_authname used to return a (const char *) to memory allocated by
krb. Somewhere along the lines this was changed so that a copy was
made, returned, and freed instead. However the const modifier was never
removed.
- halt.c did not include stdlib.h, thus missed exit() prototype
- Makefile ignores BINDIR for install.
- Makefile calls install with user/group args, thus failing for regular user.
While trying it I noticed that the Makefile does not support VPATH builds ...
it can handle small fillfactors for ordinary-sized index entries without
failing on large ones; fix nbtinsert.c to distinguish leaf and nonleaf
pages; change the minimum fillfactor to 10% for all index types.
- Replace sorted array of entries in maintenance_work_mem to binary tree,
this should improve create performance.
- More precisely calculate allocated memory, eliminate leaks
with user-defined extractValue()
- Improve wordings in tsearch2
a table. Otherwise a USING clause that yields NULL can leave the table
violating its constraint (possibly there are other cases too). Per report
from Alexander Pravking.
To this end, add a couple of columns to pg_class, relminxid and relvacuumxid,
based on which we calculate the pg_database columns after each vacuum.
We now force all databases to be vacuumed, even template ones. A backend
noticing too old a database (meaning pg_database.datminxid is in danger of
falling behind Xid wraparound) will signal the postmaster, which in turn will
start an autovacuum iteration to process the offending database. In principle
this is only there to cope with frozen (non-connectable) databases without
forcing users to set them to connectable, but it could force regular user
database to go through a database-wide vacuum at any time. Maybe we should
warn users about this somehow. Of course the real solution will be to use
autovacuum all the time ;-)
There are some additional improvements we could have in this area: for example
the vacuum code could be smarter about not updating pg_database for each table
when called by autovacuum, and do it only once the whole autovacuum iteration
is done.
I updated the system catalogs documentation, but I didn't modify the
maintenance section. Also having some regression tests for this would be nice
but it's not really a very straightforward thing to do.
Catalog version bumped due to system catalog changes.
This is an extension of pgstattuple to query information from indexes.
It supports btree, hash and gist. Gin is not supported. It scans only
index pages and does not read corresponding heap tuples. Therefore,
'dead_tuple' means the number of tuples with LP_DELETE flag.
Also, I added an experimental feature for btree indexes. It checks
fragmentation factor of indexes. If an leaf has the right link on the
next adjacent page in the file, it is assumed to be continuous (not
fragmented). It will help us to decide when to REINDEX.

I take out patch for this as a promise. This is client-build support of
MS-VC6+.
Fix for different getaddrinfo structure ordering on Win32 for IPv6.

I finally found some time to debug this, and I think I found a better
patch than the one you proposed. Mine is still hackish and is still a
workaround around a proper quoting solution, but at least it repairs
the parsing without introducing the \' quoting again.
I consider this a band-aid patch to fix the recent security update.
PostgreSQL gurus, would you consider applying this until a better
solution is found for DBMirror.pl?
Olivier, can you please confirm that the patch works for you, too?
Backpatched to 8.0.X.

Studio 2005. Basically MS defined errcode in the headers with a typedef,
so we have to #define it out of the way.
While at it, fix a function declaration in plpython that didn't match
the implementation (volatile missing).
