Export specific rows from a PostgreSQL table as INSERT SQL script

Question

I have a database schema named: nyummy and a table named cimory:

create table nyummy.cimory (
  id numeric(10,0) not null,
  name c         


        

Answer 1

Create a table with the set you want to export and then use the command line utility pg_dump to export to a file:

create table export_table as 
select id, name, city
from nyummy.cimory
where city = 'tokyo'

$ pg_dump --table=export_table --data-only --column-inserts my_database > data.sql

--column-inserts will dump as insert commands with column names.

--data-only do not dump schema.

As commented below, creating a view in instead of a table will obviate the table creation whenever a new export is necessary.
