Support inherited tables on the TPgDump component of PgDAC
Actually (v6.2.4), the PgDac TPgDump component does not generate appropriate code for inherited tables, making it useless when inherited tables are used, and we need to get the SQL script to generate the given schema.
TPgDump should support tables inheritance and:
- create base tables before inherited tables
- use the inherits clause within the table creation sql statement
- do not generate insert statements for base tables data, only for inherited tables
