Define EXEC_BACKEND in pg_config_manual.h
It was for unclear reasons defined in a separate location, which makesit more cumbersome to override for testing, and it also did not haveany prominent documentation. Move to pg_config_manual.h, wheresimilar things are already collected.The previous definition on the command-line had the effect of definingit to the value 1, but now that we don't need that anymore we justdefine it to empty, to simplify manual editing a bit.Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>Discussion:https://www.postgresql.org/message-id/flat/b7053ba8-b008-5335-31de-2fe4fe41ef0f%402ndquadrant.com
