in the Directory src/bin/pgtclsh there is a good mechanism to integrate

the
tcl-spec in the Makefile.
The patch in the attachemant does this in the src/interfaces/libpgtcl
too

Thank you

+
+For a SCADA system (Supervisory Control and Data Akquisition) which consists
+of one  master and one hot-standby server I have implemented such a
+solution. To these UNIX servers client workstations are connected (NT and/or
+UNIX). The database client programms run on client and server side.
+
+When developing this approach I had to goals in mind:
+1) Not to get dependend on the PostgreSQL sources since they change very
+dynamically.
+2) Not to get dependend on the fe/be protocol  since there are discussions
+around to change it.
+
+So the approach is quite simple: Forward all database requests to the
+standby server on TCP/IP level.
+
+On both servers the postmaster listens on port 5433 and not on 5432. On
+standard port 5432 my program listens instead. This program forks twice for
+every incomming connection. The first instance forwards all packets from the
+frontend to both backends. The second instance receives the packets from all
+backends and forwards the packets from the master backend to the frontend.
+So a frontend running on a server machine connects to port 5432 of
+localhost.
+
+On the client machine runs another program (on NT as a service). This
+program forks for every incomming connections twice. The first instance
+forwards all packets to port 5432 of the current master server and the
+second instance forwards the packets from the master server to the frontend.
+
+During standby computer startup the database of the master computer is
+dumped, zipped, copied to the standby computer, unzipped and loaded into
+that database.
+If a standby startup took place, all client connections are aborted to allow
+a login into the standby database. The frontends need to reconnect in this
+case. So the database of the standby computer is always in sync.
+
+The disadvantage of this method is that a query cannot be canceled in the
+standby server since the request key of this connections gets lost. But we
+can live with that.
+
+Both programms are able to run on Unix and on (native!) NT. On NT threads
+are created instead of forked processes.
+
+This approach is simple, but it is effective and it works.
+
+We hope to survive this way until real replication will be implemented in
+PostgreSQL.
