PostgreSQL version: 8.4.1
Operating system: Windows XP Prof.
Description: Error in PgAdmin
Details:
Since we introduced 8.4.1, we had some failures of our database. The server
remained the same, the application is the same as with our previous 8.3.x
installation.
Error 1:
"Missing ... pg_catalog"
pg_dump not possible
Fixed by "COPY table to FILE ..." for each separate table
reinstalling postgres, then restored a previous dump and run the output of
the "COPY"
