I have an existing postgres database and I want to know what are the
values of the parameters that were determined during initdb. Is there
any way to know those values ? For example, doc
http://www.postgresql.org/docs/8.1/interactive/runtime-config-resource.h
tml says that the max value of 'shared_buffers' parameter is determined
during initdb. Is there any pg_* table which I look into for such params
?

show shared_buffers;
or
show all; (for all parameters)
You can also check for postgresql.conf file in your database folder.

What you have mentioned is already there in postgresql.conf file. I want to know whats the max value allowed ? Doc seems to be saying that max allowed value is determined during initdb. How to get this max allowed value ?

As I read it, it doesn't matter what the value was originally, it's
what's in postgresql.conf _now_ that matters.
This is a resource allocation: I suspect there's no limit on how much of
your (often precious) memory you wish to set aside for this.

There is:
http://www.postgresql.org/docs/8.1/interactive/view-pg-settings.html
You could also look in the postgresql.conf file or use the SHOW
command.
http://www.postgresql.org/docs/8.1/interactive/runtime-config-file-locations.html

I normally use:
select name,current_setting(name) from pg_settings where
source='configuration file'
To figure out all the things that were set at initdb time from a new
running database. You can also look at the postgresql.conf file it
generated and search for lines that are not commented out with "#" at
the start.
