Re: Is PostgreSQL supported on RHEL6?

Hello,

Thank you for your reply. I've been largely relieved. I understood the anser was as follows:

[A1] Yes, it is safe to use PostgreSQL 8.3.12 on RHEL6.
It is recommended to rebuild it on RHEL6, however, it should be no problem to use it without rebuilding it.

[A2] N/A because the answer to Q1 is yes (safe).
Applying the newest update is always recommended. However, the newest update is not a must for RHEL6.

Tom, all, I'm sorry to ask again.

Do I need to set wal_sync_method to fdatasync in postgresql.conf if I use 8.3.12 on RHEL6? From the release note, I got the impression that even open_datasync is not a problem unless the ext4 file system is mounted with data=journal.

How about Q3?


Regards
Maumau

Now I'm trying to support both RHEL5 and RHEL6 with minimal effort (but with safety). If possible, I want to continue to use PostgreSQL 8.3.12 built on
RHEL5 for a while. Then, I'd like to ask some questions:

I'd recommend rebuilding the executables on RHEL6 if possible, but
otherwise this should be no problem.

I could build 8.3.12 successfully with 167 compilation warnings that report
"variable not used" and "uninitialized variable is used" etc. Even if I
could run PostgreSQL, I'm not sure that it is safe.

You can reasonably assume those are cosmetic.  Newer compilers tend to
be pickier about that sort of thing than older ones, so we fix those
sorts of warnings when we see them.  If any of them had represented
actual bugs, we'd have back-patched the fixes into 8.3.x.

I searched the PostgreSQL mailing lists with "RHEL6" and found the
discussion regarding wal_sync_method and O_DSYNC/O_SYNC. The following fix in 8.3.13 makes me wonder if I should update with 8.3.14 which is the latest
version of 8.3 series.

That would be a good idea in any case.

regards, tom lane
