ok, fault on my side
this is maybe better code
dd if=16403.3.orig of=16403.3 bs=8192 count=109542
dd if=/dev/zero bs=8192 count=1 >> 16403.3
dd if=16403.3.orig skip=109543 bs=8192 >> 16403.3
but now, it says
ERROR: index "day" contains unexpected zero page at block 502758
HINT: Please REINDEX it.
ok, so i did reindexing ending with following error
proxylog=# REINDEX TABLE user_record ;
ERROR: concurrent insert in progress
what should i do now?
i think it's not the problem of hw
thanks for help
