A database log is necessary for finding different statuses, errors, bad queries and any changes on the Database Server.
A Database Administrator can also log different executed queries and analyze those for performance tuning.
Following are few relevant parameters for enabling the PostgreSQL log for all the queries.
Please open your postgresql.conf file and make sure about all logs related parameter’s value which are mentioned below.
  • log_directory = ‘pg_log’ (default directory name)

  • log_statement = ‘all’ (value ‘all’ is recommended {none, ddl, mod, all})
  • logging_collector = ON
  • log_line_prefix = ‘%t %c %u ‘ (time, sessionid, user)
  • log_destination = ON (stderr,syslog,csvlog,eventlog)

PostgreSQL Index

-
Image
Indexes are special lookup tables that the database search engine can use to speed up data retrieval. Simply put, an index is a pointer to data in a table. An index in a database is very similar to an index in the back of a book. For example, if you want to reference all pages in a book that discusses a certain topic, you have to first refer to the index, which lists all topics alphabetically and then refer to one or more specific page numbers. An index helps to speed up SELECT queries and WHERE clauses; however, it slows down data input, with UPDATE and INSERT statements. Indexes can be created or dropped with no effect on the data. Creating an index involves the CREATE INDEX statement, which allows you to name the index, to specify the table and which column or columns to index, and to indicate whether the index is in ascending or descending order. Indexes can also be unique, similar to the UNIQUE constraint, in that the index prevents duplicate entries in the column or combina...

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...

PostgreSQL ALTER TABLE ... SET LOGGED / UNLOGGED

-
PostgreSQL allows one to create tables which aren't written to the Write Ahead Log, meaning they aren't replicated or crash-safe, but also don't have the associated overhead, so are good for data that doesn't need the guarantees of regular tables. But if you decided an unlogged table should now be replicated, or a regular table should no longer be logged, you'd previously have to create a new copy of the table and copy the data across. But in 9.5, you can switch between logged and unlogged using a new command: Set an unlogged table to logged: ALTER TABLE <tablename> SET LOGGED; Set a logged table to unlogged: ALTER TABLE <tablename> SET UNLOGGED; For example: # CREATE UNLOGGED TABLE messages (id int PRIMARY KEY, message text); # SELECT relname, CASE relpersistence WHEN 'u' THEN 'unlogged' WHEN 'p' then 'logged' ELSE 'unknown' END AS table_type FROM pg_class WHERE relna...
