Hello, >From time to time I face with these well-known warnings in the PostgreSQL log, i.e. Feb 28 04:21:10 db7 postgres[31142]: [2-1] WARNING: nonstandard use of escape in a string literal at character 62 Feb 28 04:21:10 db7 postgres[31142]: [2-2] HINT: Use the escape string syntax for escapes, e.g., E'\r\n'. This is fine, everybody knows about that and our PL/PgSQL developers try to make use of escape syntax. But sometimes errors occur anyway (by developers mistakes or something). So the question is: how to debug these annoying messages when pretty big application causes them? Is it possible to have a look what exact queries produced them? -- Regards, Ivan ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
