whichI now see where I may have potentially introduced the error:<br /><br /> upgrade from prostgres 9.4.4 to
9.5alpha1<br/><br /> pg_dumpall > file.sql<br /> pg_ctl stop<br /> upgrade postgres 9.5alpha1<br /> rm -r
/pgdir/*<br/> initdb -D /pgdir/<br /> pg_ctl start -D /pgdir/<br /> psql template1 -f file.sql<br /><br /><br />
upgradefrom postgres 9.5alpha1 to 9.5alpha2<br /><br /> upgrade postgres 9.5alpha1<br /> pg_ctl stop<br /> pg_ctl start
-D/pgdir/<br /><br /><br /> Now I see that not stopping the database prior to the upgrade may have<br /> introduced the
problemeventhough I don't understand the internals.  I<br /> did do another pg_ctl stop/start after upgrade just to see
ifthat would<br /> fix but it didn't.<br /></blockquote><br /> Yeah, I would say all bets are off when overwriting a
runningdatabase.<br /><br /> How are you doing the upgrade, from a package or source?<br /><br /> I now the .deb
packagesallow for running multiple versions concurrently and I believe that yum can work that way also. If building
fromsource you can do something like --prefix=/usr/local/pgsql94 in configure to separate  versions. Then you just have
tochange the port in postgresql.conf to have multiple versions on a machine. Somewhat less dangerous then deleting
