It sounds like your system defines the TCP_KEEPALIVE symbol at compile time but the kernel doesn't know it; maybe the package was compiled in a system where the kernel does support that option, and you're running it in one that doesn't? Are you getting the message in the client side or server side? If the latter, you should just set tcp_keepalives_idle to 0 in postgresql.conf. If the former, I think the only option is to fix the libpq compile. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

Actually, I find the same error in the logs for our Solaris buildfarm members. So apparently that's been going on since day one, and we hadn't noticed it, though I now find that it's been reported before: https://www.postgresql.org/message-id/CAJgtxT6QL0_Gt+TkSDw=q1=YVJkT73FoSrtStcu5Hy+-SXn8rw@mail.gmail.com Some googling turned up the tcp(7P) man page for Solaris 11: https://docs.oracle.com/cd/E36784_01/html/E36884/tcp-7p.html#REFMAN7tcp-7p and it says this: SunOS supports the keep-alive mechanism described in RFC 1122. It is enabled using the socket option SO_KEEPALIVE. Whenenabled, the first keep-alive probe is sent out after a TCP is idle for two hours. If the peer does not respond to theprobe within eight minutes, the TCP connection is aborted. You can alter the interval for sending out the first probeusing the socket option TCP_KEEPALIVE_THRESHOLD. The option value is an unsigned integer in milliseconds. The systemdefault is controlled by the TCP ndd parameter tcp_keepalive_interval. The minimum value is ten seconds. The maximumis ten days, while the default is two hours. If you receive no response to the probe, you can use the TCP_KEEPALIVE_ABORT_THRESHOLDsocket option to change the time threshold for aborting a TCP connection. The option value isan unsigned integer in milliseconds. The value zero indicates that TCP should never time out and abort the connection whenprobing. The system default is controlled by the TCP ndd parameter tcp_keepalive_abort_interval. The default is eightminutes. So apparently, Linux's TCP_KEEPIDLE corresponds to Solaris' TCP_KEEPALIVE_THRESHOLD. TCP_KEEPINTVL and TCP_KEEPCNT seem to have no direct equivalent, although TCP_KEEPALIVE_ABORT_THRESHOLD would correspond to their product. I suggest that we ought to expand the keepalive code to know about this synonym. regards, tom lane -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

Concretely, something like the attached. I have no way to test this
locally, so I'm thinking of just pushing it and seeing what the buildfarm
says.

What about defining a PG_TCP_KEEPALIVE instead?
Side note: Windows has something with a different set of options:

So that didn't work: castoroides is still showing
[5953a7e1.1fff:13] LOG: getsockopt(TCP_KEEPALIVE) failed: Option not supported by protocol
[5953a7e1.1fff:14] STATEMENT: select name, setting from pg_settings where name like 'enable%';
which implies that TCP_KEEPALIVE_THRESHOLD doesn't exist on Solaris 10.
Evidently, the logic here needs to be along the lines of
#if defined(TCP_KEEPIDLE)
...
#elif defined(TCP_KEEPALIVE_THRESHOLD)
...
#elif defined(TCP_KEEPALIVE) && defined(__darwin__)
...
Or we could make the last test be !defined(__solaris__), but I'm not
sure that's better. Anybody have an opinion?
As long as I have to touch this code again anyway, I'm also going to
look into Michael's thought of trying to reduce code duplication.
I was unhappy yesterday about how to handle the error messages,
but we could do it like this:
#if defined(TCP_KEEPIDLE)
#define PG_TCP_KEEPALIVE TCP_KEEPIDLE
#define PG_TCP_KEEPALIVE_STR "TCP_KEEPIDLE"
#elif ...
#ifdef PG_TCP_KEEPALIVE if (setsockopt(port->sock, IPPROTO_TCP, PG_TCP_KEEPALIVE, (char *)
&idle,sizeof(idle)) < 0) { elog(LOG, "setsockopt(%s) failed: %m", PG_TCP_KEEPALIVE_STR);
which doesn't seem too painful.
