Isn't it better with "autovacuum worker...." instead of "worker took too long to start; canceled" specific to "auto

Hi,

Is there a specific reason that we have a generic WARNING "worker took
too long to start; canceled" for an autovacuum worker? Isn't it better
with "autovacuum worker took too long to start; canceled"? It is
confusing to see the generic message in the server logs while
debugging an issue for a user who doesn't know the internals of
autovacuum code.

To be more informative about the message, how about the following:
1) ereport(WARNING,
(errmsg( "worker took too long to start"),
errdetail("Previous attempt to start autovacuum
worker was failed, canceled.")));
or
2) ereport(WARNING,
(errmsg( "worker took too long to start, canceled"),
errdetail("The postmaster couldn't start an
autovacuum worker.")));
or
3) ereport(WARNING,
(errmsg( "worker took too long to start, canceled"),
errdetail("Previous attempt to start autovacuum
worker was failed.")));
or
4) elog(WARNING, "postmaster couldn't start an autovacuum worker");

Thoughts?
