I stopped my slave, lowered max_connections to 100 on the primary,
restarted it, then started the slave back up and it wouldn't go:

2012-04-12 16:34:32 PDT FATAL: hot standby is not possible because
max_connections = 100 is a lower setting than on the master server (its
value was 200)

Which, OK, it _was_ 200 but now it's definitely 100. Is there a reason this
change cannot be made now?

changes needs to apply manually in standby server.

If you do not perform changes in standby server,Standby server will
shutdown automatically with above error message.

Please change "max_connection" parameter in postgresql.conf file of standby
server according primary server and then start the Standby server.
