pg_basebackup

Hello,

I am taking pg_basebackup of primary db (docker container env.) using the below command :

pg_basebackup -x -h vmzti -U replication -D /etc/postgresql/9.5/main/pg_basebkp/basekp1224 -Ft -z -P

Password:

WARNING:  skipping special file "./postgresql.conf"

WARNING:  skipping special file "./postgresql.conf"

4048512/4048512 kB (100%), 1/1 tablespace

• Getting the above warning message.
• Also the backup has been completed with only the single file  “tar -xvf base.tar.gz” as an output but there is no  tar -xvf pg_wal.tar.gz file exist.
• If we decompress the file  “tar -xvf base.tar.gz”  , I do not see the postmaster.opts file.

Note: We have the different path for the conf files :

data_directory = '/var/lib/postgresql/9.5/main'         # use data in another directory # (change requires restart)

hba_file = '/etc/postgresql/9.5/main/pg_hba.conf'       # host-based authentication file # (change requires restart)

ident_file = '/etc/postgresql/9.5/main/pg_ident.conf'   # ident configuration file # (change requires restart)

postgres=# SHOW config_file;

                 config_file

----------------------------------------------

/var/lib/postgresql/9.5/main/postgresql.conf

(1 row)

postgres=# show hba_file;

               hba_file

--------------------------------------

/etc/postgresql/9.5/main/pg_hba.conf
