Make the order of the header file includes consistent in contrib modules. The basic rule we follow here is to always first include 'postgres.h' or 'postgres_fe.h' whichever is applicable, then system header includes and then Postgres header includes.  In this, we also follow that all the Postgres header includes are in order based on their ASCII value.  We generally follow these rules, but the code has deviated in many places. This commit makes it consistent just for contrib modules. The later commits will enforce similar rules in other parts of code.

#include "utils/pg_locale.h"
Improve our #include situation by moving pointer types away from the corresponding struct definitions. This allows other headers to avoid including certain highly-loaded headers such as rel.h and relscan.h, instead using just relcache.h, heapam.h or genam.h, which are more lightweight and thus cause less unnecessary dependencies.

Reduce excessive dereferencing of function pointers It is equivalent in ANSI C to write (*funcptr) () and funcptr(). These two styles have been applied inconsistently. After discussion, we'll use the more verbose style for plain function pointer variables, to make it clear that it's a variable, and the shorter style when the function pointer is in a struct (s.func() or s->func()), because then it's clear that it's not a plain function name, and otherwise the excessive punctuation makes some of those invocations hard to read.

Make DatumGetFoo/PG_GETARG_FOO/PG_RETURN_FOO macro names more consistent. By project convention, these names should include "P" when dealing with a pointer type; that is, if the result of a GETARG macro is of type FOO *, it should be called PG_GETARG_FOO_P not just PG_GETARG_FOO. Some newer types such as JSONB and ranges had not followed the convention, and a number of contrib modules hadn't gotten that memo either. Rename the offending macros to improve consistency. In passing, fix a few places that thought PG_DETOAST_DATUM() returns a Datum; it does not, it returns "struct varlena *". Applying DatumGetPointer to that happens not to cause any bad effects today, but it's formally wrong. Also, adjust an ltree macro that was designed without any thought for what pgindent would do with it. This is all cosmetic and shouldn't have any impact on generated code.

Change TRUE/FALSE to true/false The lower case spellings are C and C++ standard and are used in most parts of the PostgreSQL sources. The upper case spellings are only used in some files/modules. So standardize on the standard spellings. The APIs for ICU, Perl, and Windows define their own TRUE and FALSE, so those are left as is when using those APIs. In code comments, we use the lower-case spelling for the C concepts and keep the upper-case spelling for the SQL concepts. Reviewed-by: Michael Paquier <michael.paquier@gmail.com>

Reduce excessive dereferencing of function pointers It is equivalent in ANSI C to write (*funcptr) () and funcptr(). These two styles have been applied inconsistently. After discussion, we'll use the more verbose style for plain function pointer variables, to make it clear that it's a variable, and the shorter style when the function pointer is in a struct (s.func() or s->func()), because then it's clear that it's not a plain function name, and otherwise the excessive punctuation makes some of those invocations hard to read.

Fix contrib/btree_gist to handle collations properly. Make use of the collation attached to the index column, instead of hard-wiring DEFAULT_COLLATION_OID. (Note: in theory this could require reindexing btree_gist indexes on textual columns, but I rather doubt anyone has one with a non-default declared collation as yet.)

Change TRUE/FALSE to true/false The lower case spellings are C and C++ standard and are used in most parts of the PostgreSQL sources. The upper case spellings are only used in some files/modules. So standardize on the standard spellings. The APIs for ICU, Perl, and Windows define their own TRUE and FALSE, so those are left as is when using those APIs. In code comments, we use the lower-case spelling for the C concepts and keep the upper-case spelling for the SQL concepts. Reviewed-by: Michael Paquier <michael.paquier@gmail.com>
