Using PostgresQL 9.4, Ubuntu 14.04, and 32 GB RAM (with modified settings in
postgresql.conf file; I think the highest allocation is 16GB).
I ran a
ts_vector creation on a text column in a table containing a little more than 1.8 billion rows. It was successful.
However, running an index on the new vector column failed in a strange way.
database_name=# create index tsv_column_idx on table_name using gin(tsv_column);
The query ran for about 56 hours in a
screen session, and then I got this message:
FATAL: terminating connection due to administrator command server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed.
Trying another query resulted in:
!> <random query>; You are currently not connected to a database.
Why would the connection have been lost? Nobody else connected to the database or made updates to the server. Is this an issue with memory allocation?
dmesg | grep -iC 3 "kill" and nothing came up.
It seems like there was some kind of shutdown error... no idea how that occurred though.
