Hi,
While playing around with where exactly to put the replication
origin/progress docs I once more noticed that the 'Server Programming'
book is a mix of different topics.
It currently contains: 35. Extending SQL 36. Triggers 37. Event Triggers 38. The Rule System 39. Procedural
Languages 40. PL/pgSQL - SQL Procedural Language 41. PL/Tcl - Tcl Procedural Language 42. PL/Perl - Perl
ProceduralLanguage 43. PL/Python - Python Procedural Language 44. Server Programming Interface 45. Background
WorkerProcesses 46. Logical Decoding 47. Replication Progress Tracking
To me at least 44 - 47 don't really fit well to the rest. I think we
either should invent a new category for them, or move them to
'Internals'. Maybe we could introduce 'Extending the Server' category
for those and a couple more? Candidates for that least seem to be
52. Writing A Procedural Language Handler
53. Writing A Foreign Data Wrapper
54. Writing A Custom Scan Provider
and arguably
57. GiST Indexes
58. SP-GiST Indexes
59. GIN Indexes
60. BRIN Indexes
as well.
Alternatively we could just move the above 'Internals' chapters into
'Server Programming'? But I think it's good to have split between C and
normal stuff there.
Also, shouldn't there at least be a link to
http://www.postgresql.org/docs/devel/static/xfunc-sql.html in
http://www.postgresql.org/docs/devel/static/xplang.html ?
