Hi. There are assorted fixes to the head branch.
1. Avoid useless reassigning var _logsegno (src/backend/access/transam/xlog.c) Commit 7d70809 <https://github.com/postgres/postgres/commit/7d708093b7400327658a30d1aa1d5e284d37622c> left a little oversight. XLByteToPrevSeg and XLByteToSeg are macros, and both assign _logsegno. So, the first assignment is lost and is useless. 2. Avoid retesting log_min_duration (src/backend/commands/analyze.c) The log_min_duration has already been tested before and the second test can be safely removed. 3. Avoid useless var declaration record (src/backend/utils/misc/guc.c) The var record is never really used. 4. Fix declaration volatile signal var (src/bin/pgbench/pgbench.c) Like how to commit 5ac9e86 <https://github.com/postgres/postgres/commit/5ac9e869191148741539e626b84ba7e77dc71670>, this is a similar case. regards, Ranier Vilela
