I am using PostgreSQL with Linux 16.04 version. I installed timescaledb in that.

After words i am trying to insert huge data into the hypertable called new_observation through observation.csv it near by approx 5 GB data, while I copy by simply copy command I will get more error afterwords I see the another way to copy huge data from go-parallel copy so I just installed go and tried something like this:

go get github.com/timescale/timescaledb-parallel-copy
gopal@addontrack:~$ timescaledb-parallel-copy --db-name testat --
schema web --table new_observation --file /tmp/observation.csv \ --
workers 2 --reporting-period 30s

panic: pq: password authentication failed for user "postgres"

goroutine 19 [running]: github.com/jmoiron/sqlx.MustConnect(0x641807, 0x8, 0xc42001e080, 0x3a, 0x0) /home/gopal/.go/src/github.com/jmoiron/sqlx/sqlx.go:652 +0x83 main.processBatches(0xc420080250, 0xc42008a060) /home/gopal/.go/src/github.com/timescale/timescaledb-parallel-copy/main.go:180 +0x63 created by main.main /home/gopal/.go/src/github.com/timescale/timescaledb-parallel-copy/main.go:105 +0x178

when I try to copy data by this way i got this error.

The postgres user by default has no password. But your server seems to expect password authentication.

The timescaledb-parallel-copy script assumes the default configuration for its connection defaults - but they can be overridden with the connection flag.

Default value:

"host=localhost user=postgres sslmode=disable"

New command (untested):

gopal@addontrack:~$ timescaledb-parallel-copy \
--connection host=localhost user=postgres password=super-secret sslmode=disable \
--db-name testat --schema web --table new_observation \
--file /tmp/observation.csv --workers 2 --reporting-period 30s
