Yes, that certainly was part of the cause. Also, if the PostgreSQL
files are backed up using tar while no database activity is happening,
there is no reason the tar restore will not work. You just create a
table with the same schema, stop the postmaster, have the backup file
replace the newly created table file, and restart the postmaster.
I can't tell you how many times I have said, "Man, whoever did this
Ingres naming schema was an idiot. Do they know how many problems they
caused for us?"
Also, Informix standard engine uses the tablename_oid setup for its
table names, and it works fine. It grabs the first 8 characters of the
table, and plops some unique number on the end of it. Works fine for
administrators.
