Create/Erase 5000 Tables in PostGRE SQL in execution Time

I am designing a system that it takes information of several databases
distributed in Interbase (RDBMS). It is a system web and each user can to do
out near 50 consultations for session. I can have simultaneously around 100
users. Therefore I can have 5000 consultations simultaneously. Each
consultation goes join to a space component in Postgis, therefore I need to
store each consultation in PostgreSQL to be able to use all the capacity of
PostGIS. The question is if for each consultation in execution time build a
table in PostGRESQL I use it and then I erase it. Is a system efficient this
way? Is it possible to have 5000 tables in PostGRESQL? How much performance?

Thanks for your help!
