Fix Windows code so that postmaster will continue rather
than exit if there is no more room in ShmemBackendArray (Magnus)
The previous behavior could lead to a denial-of-service situation if too
many connection requests arrive close together. This applies
only to the Windows port.
Fix bug introduced in 8.0 that could allow ReadBuffer
to return an already-used page as new, potentially causing loss of
recently-committed data (Tom)
Fix for protocol-level Describe messages issued
outside a transaction or in a failed transaction (Tom)
Fix character string comparison for locales that consider
different character combinations as equal, such as Hungarian (Tom)
This might require REINDEX to fix existing indexes on
textual columns.
Set locale environment variables during postmaster startup
to ensure that plperl won't change the locale later
This fixes a problem that occurred if the postmaster was
started with environment variables specifying a different locale than what
initdb had been told. Under these conditions, any use of
plperl was likely to lead to corrupt indexes. You might need
REINDEX to fix existing indexes on
textual columns if this has happened to you.
Allow more flexible relocation of installation
directories (Tom)
Previous releases supported relocation only if all installation
directory paths were the same except for the last component.
Fix longstanding bug in strpos() and regular expression
handling in certain rarely used Asian multi-byte character sets (Tatsuo)
Various fixes for functions returning RECORDs
(Tom)
Fix bug in /contrib/pgcrypto gen_salt,
which caused it not to use all available salt space for MD5 and
XDES algorithms (Marko Kreen, Solar Designer)
Salts for Blowfish and standard DES are unaffected.
Fix /contrib/dblink to throw an error,
rather than crashing, when the number of columns specified is different from
what's actually returned by the query (Joe)
