This method is not restricted to the plain text entered by the user like the previous method. This For example setting this to -c statement_timeout=5min would set the statement timeout parameter for this session to 5 minutes.. However, they are assumed to hold for purposes of query optimization, such as constraint exclusion. Also, multi-keyword operators beginning with NOT now have the precedence of their base operator (for example, NOT BETWEEN now has the same precedence as BETWEEN) whereas before they had inconsistent precedence, behaving like NOT with respect to their left operand but like their base operator with respect to their right operand. The simplest solution is to double all ' characters in the string you want to insert to table.
