Tom Lane	8255c7a5ee	Phase 2 pgindent run for v12. ... Switch to 2.1 version of pg_bsd_indent. This formats multiline function declarations "correctly", that is with additional lines of parameter declarations indented to match where the first line's left parenthesis is.

Tom Lane	382ceffdf7	Phase 3 of pgindent updates. ... Don't move parenthesized lines to the left, even if that means they flow past the right margin. By default, BSD indent lines up statement continuation lines that are within parentheses so that they start just to the right of the preceding left parenthesis. However, traditionally, if that resulted in the continuation line extending to the right of the desired right margin, then indent would push it left just far enough to not overrun the margin, if it could do so without making the continuation line start to the left of the current statement indent. That makes for a weird mix of indentations unless one has been completely rigid about never violating the 80-column limit. This behavior has been pretty universally panned by Postgres developers. Hence, disable it with indent's new -lpl switch, so that parenthesized lines are always lined up with the preceding left paren. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

Tom Lane	9aab83fc50	Redesign get_attstatsslot()/free_attstatsslot() for more safety and speed. ... The mess cleaned up in commit da0759600 is clear evidence that it's a bug hazard to expect the caller of get_attstatsslot()/free_attstatsslot() to provide the correct type OID for the array elements in the slot. Moreover, we weren't even getting any performance benefit from that, since get_attstatsslot() was extracting the real type OID from the array anyway. So we ought to get rid of that requirement; indeed, it would make more sense for get_attstatsslot() to pass back the type OID it found, in case the caller isn't sure what to expect, which is likely in binary- compatible-operator cases. Another problem with the current implementation is that if the stats array element type is pass-by-reference, we incur a palloc/memcpy/pfree cycle for each element. That seemed acceptable when the code was written because we were targeting O(10) array sizes --- but these days, stats arrays are almost always bigger than that, sometimes much bigger. We can save a significant number of cycles by doing one palloc/memcpy/pfree of the whole array. Indeed, in the now-probably-common case where the array is toasted, that happens anyway so this method is basically free. (Note: although the catcache code will inline any out-of-line toasted values, it doesn't decompress them. At the other end of the size range, it doesn't expand short-header datums either. In either case, DatumGetArrayTypeP would have to make a copy. We do end up using an extra array copy step if the element type is pass-by-value and the array length is neither small enough for a short header nor large enough to have suffered compression. But that seems like a very acceptable price for winning in pass-by-ref cases.) Hence, redesign to take these insights into account. While at it, convert to an API in which we fill a struct rather than passing a bunch of pointers to individual output arguments. That will make it less painful if we ever want further expansion of what get_attstatsslot can pass back. It's certainly arguable that this is new development and not something to push post-feature-freeze. However, I view it as primarily bug-proofing and therefore something that's better to have sooner not later. Since we aren't quite at beta phase yet, let's put it in.

Peter Eisentraut	352a24a1f9	Generate fmgr prototypes automatically ... Gen_fmgrtab.pl creates a new file fmgrprotos.h, which contains prototypes for all functions registered in pg_proc.h. This avoids having to manually maintain these prototypes across a random variety of header files. It also automatically enforces a correct function signature, and since there are warnings about missing prototypes, it will detect functions that are defined but not registered in pg_proc.h (or otherwise used).
