Jeff Davis 69e8c7cf1d Limit memory usage of pg_walinspect functions. ... GetWALRecordsInfo() and pg_get_wal_fpi_info() can leak memory across WAL record iterations. Fix this by using a temporary memory context that's reset for each WAL record iteraion. Also a use temporary context for loops in GetXLogSummaryStats(). The number of iterations is a small constant, so the previous behavior was not a leak, but fix for clarity (but no need to backport). Backport GetWALRecordsInfo() change to version 15. pg_get_wal_fpi_info() didn't exist in version 15.
