![]() Sets the client-side encoding (character set). Sets the time interval between optional checks that the client is still connected, while running queries. Deactivating validation is occasionally useful to avoid problems such as forward references when restoring function definitions from a dump. When set to off, deactivates validation of the function body string during CREATE FUNCTION. This option is ignored if the server was not compiled with Bonjour support. By default, the computer name is used, specified as an empty string. On (allow \’ always), off (reject always), safe_encoding (allow only if client encoding does not allow ASCII \ within a multibyte character) However, use of \’ creates security risks because in some client character set encodings, there are multibyte characters in which the last byte is numerically equivalent to ASCII \. The preferred, SQL-standard way to represent a quote mark is by doubling it (‘‘) but PostgreSQL has historically also accepted \’. This controls whether a quote mark can be represented by \’ in a string literal. This parameter may be set only in the nf file or on the server command line. In each round, the daemon issues VACUUM and ANALYZE commands as needed for catalog (and possibly auxiliary) tables.Ī value without units is taken to be seconds. When autovacuum=on (the default), specifies the minimum delay between autovacuum runs. Automatically analyzes the vacuumed tables.Automatically vacuums catalog tables and possibly auxiliary tables (determined by the gp_autovacuum_scope configuration parameter setting).When the daemon is running, Greenplum Database: When enabled, Greenplum Database starts up the autovacuum daemon, which operates at the database level. Value RangeĪny valid time expression (number and unit) This prevents hung clients from occupying a connection indefinitely. ![]() Maximum time to complete client authentication. Greenplum Database versions before 3.0 did not support null values in arrays, and therefore would treat NULL as specifying a normal array element with the string value ‘NULL’. By default, this is on, allowing array values containing null values to be entered. This controls whether the array input parser recognizes unquoted NULL as specifying a null array element. Setting an application name allows it to be reported in log messages and statistics views. For example, if connecting via psql, this will be set to psql. ![]() Sets the application name for a client session.
