This commit changes the definition of varlena to a typedef, so as it becomes possible to remove "struct" markers from various declarations in the code base. Historically, "struct" markers are not the project style for variable declarations, so this update simplifies the code and makes it more consistent across the board. This change has an impact on the following structures, simplifying declarations using them: - varlena - varatt_indirect - varatt_external This cleanup has come up in a different path set that played with TOAST and varatt.h, independently worth doing on its own.
