Aside from being queriable via SHOW, this value is sent to the client immediately at session startup, and again later on if the server gets promoted to primary during the session. The immediate report will be used in an upcoming patch to avoid an extra round trip when trying to connect to a primary server.

## currently, this script makes a lot of assumptions:
|
|
## in postgresql.conf.sample:
|
|
## 1) the valid config settings may be preceded by a '#', but NOT '# '
|
|
## (we use this to skip comments)
|
|
## 2) the valid config settings will be followed immediately by ' ='
|
|
## (at least one space preceding the '=')
|
|
## in guc.c:
|
|
## 3) the options have PGC_ on the same line as the option
|
|
## 4) the options have '{' on the same line as the option
|
|
|
|
## Problems
|
|
## 1) Don't know what to do with TRANSACTION ISOLATION LEVEL
|
|
|
|
## if an option is valid but shows up in only one file (guc.c but not
|
|
## postgresql.conf.sample), it should be listed here so that it
|
|
## can be ignored
