A LEFT JOIN B must produce at least as many rows as are in A ...

compressed storage works perfectly well. Might as well have a coherent
strategy for applying it, rather than the haphazard store-what-you-get
approach that was in the code before. The strategy I've set up here is
to attempt compression of any compressible index value exceeding
BLCKSZ/16, or about 500 bytes by default.

the old ones were not small enough to ensure r-tree and gist indexes would
get picked when available. These numbers are totally bogus anyway, but
in the absence of any real estimation technique, we'd like to select
indexes when available ...

per recent discussion in pgsql-odbc. Now SELECT is
a boundary but VACUUM isn't.
2) Put back the error handling behavior. When elog(ERROR)
was detected the driver automatically issue "ABORT"
if a transaction is in progress.
3) Driver version is 7.01.0003(Dave already set it but
it was put back).

such as
SELECT f1 FROM foo UNION SELECT ... ORDER BY upper(f1)
to draw
'ORDER BY on a UNION/INTERSECT/EXCEPT result must be on one of the result columns'
rather than the uninformative 'f1 not found' we were producing before.
Eventually this should actually work, but that looks much too hard to try
to implement in late beta...

specifies redundant UNIQUE conditions.

clause with an alias is a <subquery> and therefore hides table references
appearing within it, according to the spec. This is the same as the
preliminary patch I posted to pgsql-patches yesterday, plus some really
grotty code in ruleutils.c to reverse-list a query tree with the correct
alias name depending on context. I'd rather not have done that, but unless
we want to force another initdb for 7.1, there's no other way for now.

- Fixed bug in LargeObject & BlobOutputStream where the stream's output
was not flushed when either the stream or the blob were closed.
- Fixed PreparedStatement.setBinaryStream() where it ignored the length

protocol. I have left in Tom's SOCK_get_next_byte() fix, and the new
win32.mak file addition. I have also left in the 'X' connection close
fix.

GetFreeXLBuffer(): use Insert->LgwrResult instead of private LgwrResult
copy if it's more fresh (attempt to avoid acquiring info_lck/lgwr_lck).

- More TestCases implemented. Refined the test suite api's.
- Removed need for SimpleDateFormat in ResultSet.getDate() improving
performance.
- Rewrote ResultSet.getTime() so that it uses JDK api's better.
Tue Feb 13 10:25:00 GMT 2001 peter@retep.org.uk
- Added MiscTest to hold reported problems from users.
- Fixed PGMoney.
- JBuilder4/JDBCExplorer now works with Money fields. Patched Field &
ResultSet (lots of methods) for this one. Also changed cash/money to
return type DOUBLE not DECIMAL. This broke JBuilder as zero scale
BigDecimal's can't have decimal places!
- When a Statement is reused, the previous ResultSet is now closed.
- Removed deprecated call in ResultSet.getTime()
Thu Feb 08 18:53:00 GMT 2001 peter@retep.org.uk
- Changed a couple of settings in DatabaseMetaData where 7.1 now
supports those features
- Implemented the DatabaseMetaData TestCase.
Wed Feb 07 18:06:00 GMT 2001 peter@retep.org.uk
- Added comment to Connection.isClosed() explaining why we deviate from
the JDBC2 specification.
- Fixed bug where the Isolation Level is lost while in autocommit mode.
- Fixed bug where several calls to getTransactionIsolationLevel()
returned the first call's result.

as previously discussed.
It makes AIX and IRIX not use DST for dates before 1970.
The following expected files need to be removed from the regression tests,
they contain wrong results and are not needed any more.

src/test/regress/expected/tinterval-1947-PDT.out

- Add extra arg to formatStringLiteral to specify how to handle LF & TAB.
I opted for encoding them except in procedure bodies & comments
- Fixed bug in tar file input when restoring blobs

definitions from K&R to ANSI C style, and fix broken assumption that
int and long are the same datatype. This repairs problems observed
on Alpha with regexps having between 32 and 63 states.

two transactions create the same table name concurrently, the one that
fails will complain about unique index pg_class_relname_index, rather than
about pg_type_typname_index which'll confuse most people. Free side
benefit: pg_class.reltype is correctly linked to the pg_type entry now.
It's been zero in all but the preloaded pg_class entries since who knows
when.
