I often need to grab information from a Postgres database and paste it into a spreadsheet for sharing with others. Google Sheets needs the pasted data to be tab-separated in order to be correctly split into columns. This isn’t the default behaviour for psql but here’s how to configure psql’s output to get it.
At a psql prompt, switch to unaligned output
=> \a
set the field separator to a tab character:
=> \f '\t'
and turn the pager off:
=> \pset pager off
then the output from subsequent SELECT ... statements can be cleanly pasted
into your Google Doc.
