pub fn parse_oid_legacy(s: &str) -> Result<u32, ParseError>Expand description
Parses an OID from s, accepting only the i32 range.
This is the historical parse_oid behavior: values are parsed as i32
and reinterpreted as u32, so text in 2147483648..=4294967295 is
rejected even though it denotes a valid OID.
NOTE: This exists solely to keep the persisted PostgreSQL source cast
CastStringToOid evaluation-stable across releases (see the stability
contract in mz_storage_types::sources::casts). PostgreSQL replication
re-casts the old tuple on delete, so widening this cast would let a value
ingested pre-upgrade as an error be retracted post-upgrade as a value,
leaving the error stuck. Use parse_oid everywhere else.
