doc: Remove reference to trigger file regarding promotion

michaelpq · michaelpq · commit fcf46f8fb76c · 2023-12-04T08:10:32.000+09:00
The wording changed here comes from 991bfe1, when the only way to trigger a promotion was with a trigger file. There are more options to achieve this operation these days, like the SQL function pg_promote() or the command `pg_ctl promote`, so it is confusing to assume that only a trigger file is able to do the work. Note also that promote_trigger_file has been removed as of cd4329d in 16~. Author: Shinya Kato Discussion: https://postgr.es/m/201b08ea29aa61f96162080e75be503c@oss.nttdata.com Backpatch-through: 12
