[Patch] change the default value of shared_buffers in postgresql.conf.sample

Hi all

In PostgreSQL 14, The default value of shared_buffers is 128MB, but in postgresql.conf.sample, the default value of
shared_buffersis 32MB.
 

I think the following changes should be made.

File: postgresql\src\backend\utils\misc\ postgresql.conf.sample
#shared_buffers = 32MB  =>  #shared_buffers = 128MB

[PostgreSQL 14]
shared_buffers (integer)
Sets the amount of memory the database server uses for shared memory buffers. The default is typically 128 megabytes
(128MB)

--------------------------------------------------------------------
In PostgreSQL 9.2, The default value of shared_buffers is 32MB.

[PostgreSQL 9.2]
shared_buffers (integer)
Sets the amount of memory the database server uses for shared memory buffers. The default is typically 32 megabytes
(32MB)

Here is a patch.

Best Regards!
