My postgres windows client, upon receiving a query with many results, only shows some of them initially, showing -- More -- at the bottom and making you hit \"ente
-- More --
Assuming you mean psql with "my postgres windows client", you can turn off the use of the pager using the \pset command:
psql
\pset pager off
If you want to permanently turn the pager off, add that line to your psqlrc.conf file.
