Hi folks.
I'm using the following regular expression to validate some strings:

[0-9]+; [0-9]+ [0-9]+ SCHEMA - \b(information-schema|(?!pg_))\w+\b [a-zA-Z]+

8; 2615 1490850 SCHEMA - e9999 postgres
8; 2615 1490850 SCHEMA - pg_catalog postgres
8; 2615 1490850 SCHEMA - pg_temp postgres
8; 2615 1490850 SCHEMA - information-schema postgres
8; 2615 1490850 SCHEMA - information-test postgres
8; 2615 1490850 SCHEMA - information postgres
8; 2615 1490850 SCHEMA - schema postgres
8; 2615 1490850 SCHEMA - myinformation-schema postgres
8; 2615 1490850 SCHEMA - information-schemas postgres

Test string - Expected result - Given result
String 1 - Valid - Valid
String 2 - Invalid - Invalid
String 3 - Invalid - Invalid
String 4 - Invalid - Invalid
String 5 - Valid - Invalid (Error)
String 6 - Valid - Valid
String 7 - Valid - Valid
String 8 - Valid - Invalid (Error)
String 9 - Valid - Valid

Please, someone could help me to find the right pattern?
