  • Incremental backup
  • WAL hub (get-wal)
  • Compression of WAL files (bzip2, gzip or custom)
  • Backup general and disk usage information
  • Integration with standard archiving tools (e.g. tar)
  • Local recovery
  • Relocation of PGDATA and tablespaces at recovery time
  • Server diagnostics for backup

Barman 2.3 released:
5 September 2017: 2ndQuadrant is proud to announce the release of Barman version 2.3, a Backup and Recovery Manager for PostgreSQL.

This minor release introduces support for PostgreSQL 10. Following the change in naming conventions brought by PostgreSQL 10, Barman now uses the terms “WAL”, “location” instead of, respectively, “xlog” and “lsn”.

This release also adds a few additional options to the barman recover command, in order to enable or disable network compression at run-time (--network-compression and --no-network-compression) and to instruct PostgreSQL to exit recovery as soon as a consistent state is reached (--target-immediate, available from PostgreSQL 9.4).

Barman 2.3 fixes an important bug for memory consumption of parallel copy introduced in 2.2, as well as some minor bugs.

With this release Barman has dropped the support for RHEL/CentOS 5 and Ubuntu Precise (12.04) which have both reached the official end of life.

Barman 2.3 Features:

  • Add support to PostgreSQL 10
  • Follow naming changes in PostgreSQL 10:
    • The switch-xlog command has been renamed to switch-wal.
    • In commands output, the xlog word has been changed to WAL and location has been changed to LSN when appropriate.
  • Add the --network-compression/--no-network-compression options to barman recover to enable or disable network compression at run-time
  • Add --target-immediate option to recover command, in order to exit recovery when a consistent state is reached (end of the backup, available from PostgreSQL 9.4)
  • Show cluster state (master or standby) with barman status command
  • Documentation improvements
  • Bug fixes:
    • Fix high memory usage with parallel_jobs > 1 (#116)
    • Better handling of errors using parallel copy (#114)
    • Make barman diagnose more robust with system exceptions
    • Let archive-wal ignore files with .tmp extension
  • Barman Download

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

How to Get Table Size, Database Size, Indexes Size, schema Size, Tablespace Size, column Size in PostgreSQL Database

-
In this post, I am sharing few important function for finding the size of database, table and index in PostgreSQL. Finding object size in postgresql database is very important and common. Is it very useful to know the exact size occupied by the object at the tablespace. The object size in the following scripts is in GB. The scripts have been formatted to work very easily with PUTTY SQL Editor. 1. Checking table size excluding table dependency: SELECT pg_size_pretty(pg_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 238 MB (1 row) 2. Checking table size including table dependency: SELECT pg_size_pretty(pg_total_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 268 MB (1 row) 3. Finding individual postgresql database size SELECT pg_size_pretty(pg_database_size('db_name')); 4. Finding individual table size for postgresql database -including dependency index: SELECT pg_size_pretty(pg_total_rel
