* pg_rewind: Refactor the abstraction to fetch from local/libpq source.Heikki Linnakangas2020-11-041-60/+0
| | | | | | | | | | | | | | | | | This makes the abstraction of a "source" server more clear, by introducing a common abstract class, borrowing the object-oriented programming term, that represents all the operations that can be done on the source server. There are two implementations of it, one for fetching via libpq, and another to fetch from a local directory. This adds some code, but makes it easier to understand what's going on. The copy_executeFileMap() and libpq_executeFileMap() functions contained basically the same logic, just calling different functions to fetch the source files. Refactor so that the common logic is in one place, in a new function called perform_rewind().

* Make the order of the header file includes consistent in non-backend modules.Amit Kapila2019-10-251-1/+1
| | | | | | | | | | | | Similar to commit 7e735035f2, this commit makes the order of header file inclusion consistent for non-backend modules. In passing, fix the case where we were using angle brackets (<>) for the local module includes instead of quotes ("").

* Remove useless duplicate inclusions of system header files.Tom Lane2017-02-251-1/+0
| | | | | | | | | | | | | | | | c.h #includes a number of core libc header files, such as <stdio.h>. There's no point in re-including these after having read postgres.h, postgres_fe.h, or c.h; so remove code that did so. While at it, also fix some places that were ignoring our standard pattern of "include postgres[_fe].h, then system header files, then other Postgres header files". While there's not any great magic in doing it that way rather than system headers last, it's silly to have just a few files deviating from the general pattern. (But I didn't attempt to enforce this globally, only in files I was touching anyway.) I'd be the first to say that this is mostly compulsive neatnik-ism, but over time it might save enough compile cycles to be useful.

* Minor cleanup of pg_rewind.Heikki Linnakangas2015-04-151-2/+2
| | | | | | | | | | Update comments and function names to use the terms "source" and "target" consistently. Some places were calling them remote and local instead, which was confusing. Fix incorrect comment in extractPageInfo on database creation record - it was wrong on what happens for databases created in the target that don't exist in source.
