Restrict number of connections to specific table

Hi - apologies if this question has a painfully obvious answer. I put
the N in novice regarding postgresql.

I use postgres with the spatial extension, postgis.

I have some licenced geospatial data. The licence terms state that only
"one user can access the data at one time".

I want to add this data to the collection of spatially-enabled postgis
tables that I serve to my enterprise, where users access and consume
postgis data tables via GIS clients.

Can I put a constraint on a specific table to restrict the number of
concurrent connections to 1, which will allow me to adhere to the data
licencing terms?

If not, is there an alternative solution to serve up the data via a
PostgreSQL table and still keep within the data licence terms?

Any help is much appreciated.

Cheers

Sam
