No, it is just that the program we use to interact with our database (or it may be the database program itself - I'm not sure exactly) can only have 64 users on it any time. I am working on increasing that number but it is a money issue, its like $2,000 per license for each additional session.

alter_database
ALTER
DATABASE(7) PostgreSQL 9.2.7 Documentation ALTER DATABASE(7)
NAME
ALTER_DATABASE - change a database
SYNOPSIS
ALTER DATABASE name [ [ WITH ] option [ ... ] ]
where option can be:
CONNECTION LIMIT connlimit
ALTER DATABASE name RENAME TO new_name
ALTER DATABASE name OWNER TO new_owner
ALTER DATABASE name SET TABLESPACE new_tablespace
ALTER DATABASE name SET configuration_parameter { TO | = } { value | DEFAULT }
ALTER DATABASE name SET configuration_parameter FROM CURRENT
ALTER DATABASE name RESET configuration_parameter
ALTER DATABASE name RESET ALL
DESCRIPTION
ALTER DATABASE changes the attributes of a database.
The first form changes certain per-database settings. (See below for details.) Only the database owner or a superuser can change these
settings.
The second form changes the name of the database. Only the database owner or a superuser can rename a database; non-superuser owners must
also have the CREATEDB privilege. The current database cannot be renamed. (Connect to a different database if you need to do that.)
The third form changes the owner of the database. To alter the owner, you must own the database and also be a direct or indirect member of
the new owning role, and you must have the CREATEDB privilege. (Note that superusers have all these privileges automatically.)
The fourth form changes the default tablespace of the database. Only the database owner or a superuser can do this; you must also have
create privilege for the new tablespace. This command physically moves any tables or indexes in the database's old default tablespace to
the new tablespace. Note that tables and indexes in non-default tablespaces are not affected.
The remaining forms change the session default for a run-time configuration variable for a PostgreSQL database. Whenever a new session is
subsequently started in that database, the specified value becomes the session default value. The database-specific default overrides
whatever setting is present in postgresql.conf or has been received from the postgres command line. Only the database owner or a superuser
can change the session defaults for a database. Certain variables cannot be set this way, or can only be set by a superuser.
PARAMETERS
name
The name of the database whose attributes are to be altered.
connlimit
How many concurrent connections can be made to this database. -1 means no limit.
new_name
The new name of the database.
new_owner
The new owner of the database.
new_tablespace
The new default tablespace of the database.
configuration_parameter, value
Set this database's session default for the specified configuration parameter to the given value. If value is DEFAULT or, equivalently,
RESET is used, the database-specific setting is removed, so the system-wide default setting will be inherited in new sessions. Use
RESET ALL to clear all database-specific settings. SET FROM CURRENT saves the session's current value of the parameter as the
database-specific value.
See SET(7) and Chapter 18, Server Configuration, in the documentation for more information about allowed parameter names and values.
NOTES
It is also possible to tie a session default to a specific role rather than to a database; see ALTER ROLE (ALTER_ROLE(7)). Role-specific
settings override database-specific ones if there is a conflict.
EXAMPLES
To disable index scans by default in the database test:
ALTER DATABASE test SET enable_indexscan TO off;
COMPATIBILITY
The ALTER DATABASE statement is a PostgreSQL extension.
