Hi, today I needed to re-create certain records deleted from a mysql database, so I restored an old backup, opened a terminal and logged in to the old database using the "mysql" command line utility, then opened a new terminal with mysql connected to the production database. Then did a "select * from table where id=xxx \G;" to display a record, then, on the other terminal I had to write "insert into table(field1, field2,...,fieldN) values(...);" for each record.

While doing that I tought of a neat feature that psql could provide, that is something like "\insert for select * from table where id=xxx;" this should create the insert command for the requested query.

You can do something like given below:
CREATE TABLE temp_generate_inserts AS SELECT * FROM table id=xx
Then use pg_dump --column-inserts  -t temp_generate_inserts db1|psql db2
and later you can drop temp_generate_inserts table.

With this you can also explore dblink_build_sql_insert function which comes with dblink module:
http://www.postgresql.org/docs/9.3/interactive/contrib-dblink-build-sql-insert.html
