Hello!

There is a problem CREATE DATABASE does not copy configuration
parameters values:

[ACTIONS]
ui_dev_12=# create database bash_test;
CREATE DATABASE
ui_dev_12=# alter database bash_test set log_min_messages TO 'debug5';
ALTER DATABASE
ui_dev_12=# create database bash_test2 template = bash_test;
CREATE DATABASE
ui_dev_12=# \q
$ psql bash_test2
psql (9.3.1)
Type "help" for help.

bash_test2=# show log_min_messages;

[EXPECTED]
log_min_messages
------------------
debug5
(1 row)

[RECIEVED]
log_min_messages
------------------
warning
(1 row)

Please could you ether fix this behavior or at least describe current
behavior in docs.

Regards,
Alexey Bashtanov

Is there a reason for this? I would love for these types of variables to be
copied into backups, restored from dumps, etc.
