I have encountered a problem while restoring the database. There is a
table that contains XML data (BLOB), ~ 3 000 000 records, ~ 5.5Gb of
data. pg_restore has been running for a week without any considerable
progress. There are plenty of lines like these in the log:
pg_restore: processing item 3125397 BLOB 10001967
pg_restore: executing BLOB 10001967
CPU usage is 100% always. The total database size is about 100 Gb and it
restores in an hour or so without BLOBs.
