Which option do I have to modify to see more records without press `q`
You can turn off (and on) the paging in psql:

\pset pager [on|off]


If you don't specify on or off, the command will toggle the setting.  (More on \pset in the documentation.)
In the shell, you can even set the pager you want to use:

PAGER=/usr/bin/less


If you start psql after this, less will be your pager.
