- * pmod.h --
- * POSTGRES processing mode definitions.
- *
- * 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.
