Fix segmentation fault in MergeInheritedAttribute()
While converting a pg_attribute tuple into a ColumnDef,
ColumnDef::compression remains NULL if there is no compression method
set fot the attribute. Calling strcmp() with NULL
ColumnDef::compression, when comparing compression methods of parents,
causes segmentation fault in MergeInheritedAttribute(). Skip
comparing compression methods if either of them is NULL.
