There are a few ways, from memory (so I might have the odd syntax error):


To replicate a table run pg_dump on one machine pointing at the host/db
to export & pipe the output to psql -f with the host & name of the
target db.

pg_dump -h host0 -d db0 -t table ... | psql -h host1 -d db1 -f


you can do similar data streams from one db to another with (if the
target table exists):

psql .... -c "copy table to STDOUT ..." | psql ... -c "copy table from
STDOUT ..."


to do this with the results of a query to subset the data will require
the pre-building of the target table, but you can do:

psql -h host0 -d db0 -F"|" -Atc "select.....;" | psql -h host1 -d db1 -c
"copy table from STDIN with delimiters = '|';"
