Thomas Munro	dfd0121dc7	Move some md.c-specific logic from smgr.c to md.c. ... Potential future SMGR implementations may not want to create tablespace directories when creating an SMGR relation. Move that logic to mdcreate(). Move the initialization of md-specific data structures from smgropen() to a new callback mdopen().

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	be76af171c	Initial pgindent run for v12. ... This is still using the 2.0 version of pg_bsd_indent. I thought it would be good to commit this separately, so as to document the differences between 2.0 and 2.1 behavior. Discussion: https://postgr.es/m/16296.1558103386@sss.pgh.pa.us	7 years ago
Thomas Munro	3eb77eba5a	Refactor the fsync queue for wider use. ... Previously, md.c and checkpointer.c were tightly integrated so that fsync calls could be handed off and processed in the background. Introduce a system of callbacks and file tags, so that other modules can hand off fsync work in the same way. For now only md.c uses the new interface, but other users are being proposed. Since there may be use cases that are not strictly SMGR implementations, use a new function table for sync handlers rather than extending the traditional SMGR one. Instead of using a bitmapset of segment numbers for each RelFileNode in the checkpointer's hash table, make the segment number part of the key. This requires sending explicit "forget" requests for every segment individually when relations are dropped, but suits the file layout schemes of proposed future users better (ie sparse or high segment numbers).
