|
|
* Description:
|
|
* There are four processing modes in POSTGRES. They are NoProcessing
|
|
* or "none," BootstrapProcessing or "bootstrap," InitProcessing or
|
|
* "initialization," and NormalProcessing or "normal."
|
|
*
|
|
* If a POSTGRES binary is in normal mode, then all code may be executed
|
|
* normally. In the none mode, only bookkeeping code may be called. In
|
|
* particular, access method calls may not occur in this mode since the
|
|
* execution state is outside a transaction.
|
|
*
|
|
* The final two processing modes are used during special times. When the
|
|
* system state indicates bootstrap processing, transactions are all given
|
|
* transaction id "one" and are consequently guarenteed to commit. This mode
|
|
* is used during the initial generation of template databases.
|
|
*
|
|
* Finally, the execution state is in initialization mode until all normal
|
|
* initialization is complete. Some code behaves differently when executed in
|
|
* this mode to enable system bootstrapping.
