Insert text with single quotes in PostgreSQL

Question

I have a table test(id,name).

I need to insert values like: user\'s log, \'my user\', customer\'s.

Answer 1

According to PostgreSQL documentation (4.1.2.1. String Constants):

 To include a single-quote character within a string constant, write two 
 adjacent single quotes, e.g. 'Dianne''s horse'.

See also the standard_conforming_strings parameter, which controls whether escaping with backslashes works.
