Hi,
See attached screenshots. In pgAdmin3 the number format would stay in the "general" format no matter how large, in pgAdmin4 larger record numbers show in exponential format, (BTW, the most user-friendly format is a general format with thousand separators)
Note also that I cannot see any way to COUNT records in pgAdmin4 (and fill in that field in the properties), obviously beyond writing a tiny query for it. In pgAdmin3 you would right-click on any table and select "count".
Regards
Calle
