While updating the row filter patch [1] (because it also uses these
structures), I noticed that you use PublicationRelInfo as a type name instead
of PublicationRelationInfo. I choose the latter because there is already a data
structure named PublicationRelInfo (pg_dump.h). It is a client-side data
structure but I doesn't seem a good practice to duplicate data structure names
over the same code base.
