2013-01-01Update copyrights for 2013Bruce Momjian
Fully update git head, and update back branches in ./COPYRIGHT and legal.sgml files.
2012-11-29Basic binary heap implementation.Robert Haas
There are probably other places where this can be used, but for now, this just makes MergeAppend use it, so that this code will have test coverage. There is other work in the queue that will use this, as well. Abhijit Menon-Sen, reviewed by Andres Freund, Robert Haas, Álvaro Herrera, Tom Lane, and others.

2011-12-07Create a "sort support" interface API for faster sorting.Tom Lane
This patch creates an API whereby a btree index opclass can optionally provide non-SQL-callable support functions for sorting. In the initial patch, we only use this to provide a directly-callable comparator function, which can be invoked with a bit less overhead than the traditional SQL-callable comparator. While that should be of value in itself, the real reason for doing this is to provide a datatype-extensible framework for more aggressive optimizations, as in Peter Geoghegan's recent work. Robert Haas and Tom Lane
2011-09-01Remove unnecessary #include references, per pgrminclude script.Bruce Momjian
2011-07-04Move Trigger and TriggerDesc structs out of rel.h into a new reltrigger.hAlvaro Herrera
This lets us stop including rel.h into execnodes.h, which is a widely used header.
2011-04-12Pass collations to functions in FunctionCallInfoData, not FmgrInfo.Tom Lane
Since collation is effectively an argument, not a property of the function, FmgrInfo is really the wrong place for it; and this becomes critical in cases where a cached FmgrInfo is used for varying purposes that might need different collation settings. Fix by passing it in FunctionCallInfoData instead. In particular this allows a clean fix for bug #5970 (record_cmp not working). This requires touching a bit more code than the original method, but nobody ever thought that collations would not be an invasive patch...

2011-03-26Clean up cruft around collation initialization for tupdescs and scankeys.Tom Lane
I found actual bugs in GiST and plpgsql; the rest of this is cosmetic but meant to decrease the odds of future bugs of omission.
2011-02-08Per-column collation supportPeter Eisentraut
This adds collation support for columns and domains, a COLLATE clause to override it per expression, and B-tree index support. Peter Eisentraut reviewed by Pavel Stehule, Itagaki Takahiro, Robert Haas, Noah Misch

2010-10-14Support MergeAppend plans, to allow sorted output from append relations.Tom Lane
This patch eliminates the former need to sort the output of an Append scan when an ordered scan of an inheritance tree is wanted. This should be particularly useful for fast-start cases such as queries with LIMIT. Original patch by Greg Stark, with further hacking by Hans-Jurgen Schonig, Robert Haas, and Tom Lane.
