Then this should be changed to return true, since we will be mostly compliant (probably more compliant than many other databases) And since this is a requirement for all JDBC drivers we need to get to the point where we can return true.

    How many active connection can we have at a time to this database? Well, since it depends on postmaster, which just does a listen() followed by an accept() and fork(), its basically very high. Unless the system runs out of processes, it can be 65535 (the number of aux. ports on a TCP/IP system). I will return 8192 since that is what even the largest system can realistically handle,

    Does a data definition statement within a transaction force the transaction to commit? It seems to mean something like:
```
 CREATE TABLE T (A INT);
 INSERT INTO T (A) VALUES (2);
 BEGIN;
 UPDATE T SET A = A + 1;
 CREATE TABLE X (A INT);
 SELECT A FROM T INTO X;
 COMMIT;
 
```
    Does the CREATE TABLE call cause a commit? The answer is no.
