Thank you for your reply, Tom. I had not appreciated the difference
between \COPY and COPY. The psql command is executed on the client; the
import data are on the client, so I ought to use \COPY.
Strangely, cat event.csv |psql -c "COPY ... worked, presumably
because both the COPY command and data came from the same source (client
stdin).
I changed event.sql (3 lines):
\COPY (event_id, event_name) FROM STDIN DELIMITER AS ',' NULL AS ''
Now I am getting error messages:
psql:event.sql:1: \copy:parse error at end of line
psql:event.sql:4: ERROR:syntax error at or near "event_id" LINE 1:
(event_id,
When I remove the linefeeds I don't get errors but it does not import
anything.
I'd like the store the COPY command in a separate file without
specifying an input file name. I want to feed it the data from the
shell script that calls psql -f.
