Hard disk containing PostgreSql 8.1 database on Windows crashes and there
was no new
backup copy.
I installed 8.1.9 to new computer and copied data directory from crashed
disk to it.
data directory contains a lot of files with a lot of data.
Trying to connect to template0 or any other database in this cluster causes
error
Error connecting to the server: FATAL: index "pg_authid_rolname_index" is
not a btree
How to recover data from this cluster ?
Andrus.
