Обсуждение: pgsql: Improve scripting language in pgbench
Improve scripting language in pgbench Added: - variable now might contain integer, double, boolean and null values - functions ln, exp - logical AND/OR/NOT - bitwise AND/OR/NOT/XOR - bit right/left shift - comparison operators - IS [NOT] (NULL|TRUE|FALSE) - conditional choice (in form of when/case/then) New operations and functions allow to implement more complicated test scenario.

Jan 09 11:49:51 # doesn't match '(?-xism:command=29.: double 1e\+30\b)' I think you need to put "0?" back into the pattern like in the attached. -- Thomas Munro http://www.enterprisedb.com
