From: Alexander Korotkov Date: Mon, 7 Apr 2025 13:28:54 +0000 (+0300) Subject: Remove GUC_NOT_IN_SAMPLE from enable_self_join_elimination X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=717d0e8dd945edea7c7e875bdb2553238a94f885;p=users%2Frhaas%2Fpostgres.git Remove GUC_NOT_IN_SAMPLE from enable_self_join_elimination fc069a3a6319 implements Self-Join Elimination (SJE) and provides a new GUC variable: enable_self_join_elimination. This new GUC variable was marked as GUC_NOT_IN_SAMPLE. However, enable_self_join_elimination is documented and is not different from any other enable_* GUCs. Thus, remove GUC_NOT_IN_SAMPLE from it and add it to the postgresql.conf.sample.
