I have been receiving warning messages recently:
WARNING: database "mydb" must be vacuumed within xxxx transactions HINT: To avoid a database shutdown, execute a full-database VACUUM in "mydb".
So I have tryed VACUUM, VACUUM FULL and VACUUM FULL FREEZE but all of the options end up with the same error:
ERROR: could not open file "base/19069/26252": No such file or directory
So... what can I do? I am desperate right now, I don't want the db to shutdown!
