PostgreSQL Installation Mostly Faced Troubleshooting

-
--mode unattended Authentication Errors
Authentication errors from component modules during unattended installations may indicate that the specified values of --servicepassword or --superpassword may be incorrect.

 Errors During an PostgreSQL Installation on Windows
If you encounter an error during the installation process on a Windows system, exit the installation, and ensure that your version of Windows is up-to-date. After applying any outstanding operating system updates, re-invoke the PostgreSQL installer.

Applications Fail to Launch During a PostgreSQL Installation on Linux/Unix

 If applications fail to launch (such as Stack Builder or your web browser) during the installation process on a Linux or Unix system, verify that the xdg-open program is on your system. If xdg-open is missing, install the xdg-utils package.

 If you are using the GNOME desktop, load the root profile before running the PostgreSQL installation script. To load the root profile, issue the command, su - root instead of su root before installing PostgreSQL.

postgreSQL Compress format backup

-
The -F option on pg_dump allows you to specify the format of the output. The default output is plain-text. That’s what you get when you do this: pg_dump bacula > bacula.sql and is functionally equivalent to doing: pg_dump -Fp bacula > bacula.sql There are other formats (directory, tar), but today I’m concerned with the custom (c) option. By default, this output is also compressed (see the -Z option). What is of most value is the ability to use  pg_restore  with the custom output. What’s the big deal about custom format? The more interesting option on pg_restore was -j. This allows you to run multiple concurrent jobs for the loading of data and building of indexes. This can greatly reduce the amount of time needed to restore a large database if your server has multiple processors. pg_restore can be much more useful than just doing: psql bacula < bacula.sql With pg_restore you can be very selective about what you restore. See the -L and -l options. How much do

How to find the server is whether standby (slave) or primary(master) in Postgresql replication ?

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)

7 Steps to configure BDR replication in postgresql

-
Image
 The  BDR  (Bi-Directional Replication) project adds multi-master replication to PostgreSQL 9.4.  Postgres-BDR has a lower impact on the masters(s) than trigger-based replication solutions. There is no write-amplification, as it does not require triggers to write to queue tables in order to replicate writes.   Here We are using  postgres version 9.4.12 and bdr version 1.0.2. for configuring  multi master replication . Simply Following 7 steps you can configure the multi master replication in postgresql. To download the bdr in below link. .   https://github.com/2ndQuadrant/bdr/archive/bdr-pg/REL9_4_12-1.tar.gz $ tar -xzvf REL9_4_12-1.tar.gz $ wget https://github.com/2ndQuadrant/bdr/archive/bdr-plugin/1.0.2.tar.gz $ tar -xzvf 1.0.2.tar.gz 1. To install BDR. $ cd ~/bdr-bdr-pg-REL9_4_12-1 $ ./configure --prefix=/usr/lib/postgresql/9.4 --enable-debug --with-openssl $ make -j4 -s install-world $ cd ~/bdr-bdr-plugin-1.0.2 $ PATH=/usr/lib/postgresql/9.4/bin:"$PATH" ./c
