Hi,

I have fixed the following issues in the v63 version patch attached:
1) pg_dump was dumping the internally generated event triggers and the
create publication with ddl option which resulted in creating multiple
event triggers while restoring, this patch now addresses this by
skipping the dump of internally generated event triggers
2) Restoring of non ddl publication was not correct, this is handled
3) There were few indent issues while applying 003 patch.

These are handled in the v63 version attached.

Regards,
Vignesh
