Update PostgreSQL table through CSV/TSV/TXT file via command line on Linux

1. In interactive mode:

pg-cmd> load loadtype=update
      > updatekey=id
      > table=media_messages 
      > datafile=/data/media_messages.csv 
      > delimiter=, 
      > quote=" 
      > header=y;

2. In batch mode:

pg-cmd dsn="pan:withdata@192.168.0.102/test" task=load loadtype=update updatekey=id table=media_messages datafile=/data/media_messages.csv delimiter=, quote=" header=y quit=y

“loadtype=update” will update row in table by “updatekey” id, not insert.

See parameters detail.
