Hi, hackers I have a problem about XLogReader callback system
In xlog.c, function StartupXLOG
xlogreader =
XLogReaderAllocate(wal_segment_size, NULL,
XL_ROUTINE(.page_read =
&XLogPageRead,
.segment_open = NULL,
.segment_close = wal_segment_close),
&private);
XLogPageReader uses readFile to store the fd, and I can't find any location to
set the value of seg.ws_file.
Is it necessary to set a segment_close callback?
Best regards
Wang
