Beyond 21474, the number of accounts exceed the range for int4. Change the initialization code to use bigint for account id columns when scale is large enough, and switch to using int64s for the variables in pgbench code. The threshold where we switch to bigints is set at 20000, because that's easier to remember and document than 21474, and ensures that there is some headroom when int4s are used. Greg Smith, with various changes by Euler Taveira de Oliveira, Gurjeet Singh and Satoshi Nagayasu.
The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "gmake all" and "gmake
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
