Dear Fujii-san,
I attached new version, that almost all codes
moved from libpq to postgres_fdw.
Now we can accept four types of escapes.
All escapes will be rewritten to connection souce's information:
* application_name,
* user name,
* database name, and
* backend's pid.
These are cannot be set by log_line_prefix, so I think it is useful.
We can use escape sequences in two ways:
* Sets postgres_fdw.application_name GUC paramter, or
* Sets application_name option in CREATE SERVER command.
Which version do you like?
Best Regards,
Hayato Kuroda
