For the ignorant, are you able to explain why naming files
'<table_name>_<IOD>' is not acceptable? This seems to satisfy both
requirements (and seemed to be the conclusion of the previous discussion).
I presume I have missed something, and assume there is a good reason for
the '<IOD>' naming convention, so if that is the final choice, would it be
hard to have a file header containing details about the table/index/thing
the the file contains and it's OID. In this way, a future pd_dumpfile
command can tell us what our backed up file '1FA12347.dat' is supposed to
contain?
