Subject: How do I upgrade Postgres database in Cygwin?
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

I updated some Cygwin packages and now I can't start Postgres:

     $ /usr/sbin/postmaster
     FATAL:  database files are incompatible with server
     DETAIL:  The data directory was initialized by PostgreSQL version 
8.2, which is not compatible with this version 9.2.4.

I tried 
[pg_upgrade](http://www.postgresql.org/docs/9.2/static/pgupgrade.html) 
but you need to specify both the old and new binary. Plus, pg_upgrade 
says it only works with 8.3.

I thought I could use setup-x86.exe to pick the previous version, which 
is 8.2.11-1, however when I install that, then I can't start Postgres:


     $ /usr/sbin/postgres.exe
     Bad system call (core dumped)
