Andrew Dunstan	2e74c53ec1	Provide for binary input/output of enums, to fix complaint from Merlin Moncure. ... This just provides text values, we're not exposing the underlying Oid representation. Catalog version bumped.	19 years ago
Tom Lane	31edbadf4a	Downgrade implicit casts to text to be assignment-only, except for the ones ... from the other string-category types; this eliminates a lot of surprising interpretations that the parser could formerly make when there was no directly applicable operator. Create a general mechanism that supports casts to and from the standard string types (text,varchar,bpchar) for *every* datatype, by invoking the datatype's I/O functions. These new casts are assignment-only in the to-string direction, explicit-only in the other, and therefore should create no surprising behavior. Remove a bunch of thereby-obsoleted datatype-specific casting functions. The "general mechanism" is a new expression node type CoerceViaIO that can actually convert between *any* two datatypes if their external text representations are compatible. This is more general than needed for the immediate feature, but might be useful in plpgsql or other places in future. This commit does nothing about the issue that applying the concatenation operator || to non-text types will now fail, often with strange error messages due to misinterpreting the operator as array concatenation. Since it often (not always) worked before, we should either make it succeed or at least give a more user-friendly error; but details are still under debate. Peter Eisentraut and Tom Lane	19 years ago
Andrew Dunstan	325feaef7f	Check length of enum literals on definition and input to make sure they will fit in a name field and not cause syscache errors.	19 years ago
Tom Lane	57690c6803	Support enum data types. Along the way, use macros for the values of ... pg_type.typtype whereever practical. Tom Dunstan, with some kibitzing from Tom Lane.	19 years ago
