Not sure how others feel about that, but I am OK with camel-case style
for the modules.

Perhaps we could just leave it out, then, adding a comment instead.

Shouldn't dblink use two different strings?

Same about autoprewarm.c. The same flag is used in two different code
paths. If removed from the patch, no need to do that, of course.
+static uint32 wait_event_info_connect = 0;
+static uint32 wait_event_info_receive = 0;
+static uint32 wait_event_info_cleanup_receive = 0;
Perhaps such variables could be named with shorter names proper to
each module, like pgfdw_we_receive, etc.

"Waiting for transaction abort on remote server"?
