Go code generation fails for PostgreSQL ENUM values with '+' and '-' due to duplicate constant names #4515
Description
Version
1.31.1
Version
- sqlc: v1.31.1
- PostgreSQL: 18x
- Go: go1.26.1 windows/amd64
What happened?
When using a PostgreSQL ENUM that contains values with + and - (e.g. blood groups), sqlc generates duplicate Go constant names, causing the generated code to fail to compile.
For example:
CREATE TYPE blood_group_type AS ENUM (
'A+',
'A-',
'B+',
'B-',
'AB+',
'AB-',
'O+',
'O-'
);

Kindly update this issue after the PR is merged so I can verify it in the appropriate release.

Hi, just following up on this PR. It has been open for several months, and we're still affected by the PostgreSQL ENUM constant-name collision described in #4515. Is there any update on the review or merge timeline? Thanks!
