FOR loops are giving weird syntax errors. Restructure parsing of FOR
loops so that the integer-loop-vs-query-loop decision is driven off
the presence of '..' between IN and LOOP, rather than the presence
of a matching record/row variable name. Hopefully this will make the
behavior a bit more transparent.
better SQL compliance in this area, per recent discussion. Mark related
operators as commutators where possible. (The system doesn't actually care
about commutator marking for operators not returning boolean, at the moment,
but this seems forward-thinking and besides it made it easier to verify
that we hadn't missed any.)
Also, remove interval-minus-time and interval-minus-timetz operators.
I'm not sure how these got in, but they are nonstandard and had very
obviously broken behavior. (minus is not commutative in anyone's book.)
I doubt anyone had ever used 'em, because we'd surely have gotten a bug
report about it if so.
From an idea of Bruce, the attached patch implements the function
pg_tablespace_databases(oid) RETURNS SETOF oid
which delivers as set of database oids having objects in the selected
tablespace, enabling an admin to examine only the databases affecting
the tablespace for objects instead of scanning all of them.
initdb forced
for cleaning up. It seems possible that the memory contexts SPI_finish
would try to touch are already gone; and there's no need for SPI itself
to delete them, since the containing contexts will surely be going away
anyway at transaction end.
plperlNG. Review and minor cleanup/improvements by Joe Conway.
Summary of new functionality:
- Shared data space and namespace. There is a new global variable %_SHARED
that functions can use to store and save data between invocations of a
function, or between different functions. Also, all trusted plperl function
now share a common Safe container (this is an optimization, also), which
they can use for storing non-lexical variables, functions, etc.
- Triggers are now supported
- Records can now be returned (as a hash reference)
- Sets of records can now be returned (as a reference to an array of hash
references).
- New function spi_exec_query() provided for performing db functions or
getting data from db.
- Optimization for counting hash keys (Abhijit Menon-Sen)
- Allow return of 'record' and 'setof record'
an empty input string causes an empty output string to be returned, instead of
throwing an ERROR -- per complaint from Aaron Hillegass, and consistent with
double metaphone. Fix examples in README.soundex pointed out by James Robinson.
performance front, but with feature freeze upon us I think it's time to
drive a stake in the ground and say that this will be in 7.5.
Alvaro Herrera, with some help from Tom Lane.
Note that this still has some bugs. The functionality is there though, it's just a matter of fixing the bugs now.
Cleaned up error handling in preprocessor.
only because 14627 still contained the same node that BitWithoutLength had
just produced. Make it more transparent. Also adjust ConstCharacter
to be coded the same way for consistency.
- Variables that are out of scope, were not removed all the time.
- Make a varchar NULL set everything to 0 when not using indicators.
- Synced parser.
specified in just one place and adhered to exactly, rather than just more
or less. A side effect is to increase PGSTAT_ACTIVITY_SIZE (maximum
reported query length) from 256 to nearly 1000.
aggregates, conversions, functions, operators, operator classes,
schemas, types, and tablespaces. Fold the existing implementations
of alter domain owner and alter database owner in with these.

This eliminates the assumption that a serial column's sequence will
have the same name on reload that it was given in the original database.
