|
|
*
|
|
* 1. Declare a global variable of type bool, int, double, or char*

|
* and make use of it.

|
*
|
|
* 2. Decide at what times it's safe to set the option. See guc.h for
|
|
* details.
|
|
*
|
|
* 3. Decide on a name, a default value, upper and lower bounds (if
|
|
* applicable), etc.
|
|
*
|
|
* 4. Add a record below.
|
|
*
|
|
* 5. Add it to src/backend/utils/misc/postgresql.conf.sample, if
|
|
* appropriate.
|
|
*
|
|
* 6. Don't forget to document the option (at least in config.sgml).
|
|
*
|
|
* 7. If it's a new GTMOPT_LIST option you must edit pg_dumpall.c to ensure
|
|
* it is not single quoted at dump time.
