bdftruncate

- 
bdftruncate -V (return code: 1)

Illegal threshold --version
Usage: bdftruncate [+w|-w] threshold <source.bdf >destination.bdf

Example:

  bdftruncate 0x3200 <6x13.bdf >6x13t.bdf

will generate the file 6x13t.bdf in which all glyphs with codes
>= 0x3200 will only be stored unencoded (i.e., ENCODING -1).
Option -w removes East Asian Wide and East Asian FullWidth characters
(default if threshold <= 0x3200), and option +w keeps them.
bdftruncate --help (return code: 1)

Method 1 You can check the mode of the server using "pg_controldata". [pgsql@test~]$ pg_controldata /usr/local/pgsql/data84/ Database cluster state: in archive recovery --> This is Standby Database Database cluster state: in production --> This is Production Database [Master] Method 2 You can use pg_is_in_recovery() which returns True if recovery is still in progress(so the server is running in standby mode or slave) postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- t (1 row) If Return    false   so the server is running in primary mode or master postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- f (1 row)
