Production down (Termin/Fristen list returning 503) since 13:28 UTC on
my own 6c40823 deploy:
ERROR service: prepare list deadlines:
pq: syntax error at or near ":" at position 24:68 (42601)
Root cause: sqlx's named-parameter parser scans for `:identifier`
tokens and rewrites them into positional placeholders. The Postgres
cast operator `::` is two consecutive `:`. So `completed_at::date`
gets read as `completed_at:` + `:date` placeholder; the parser strips
the cast and leaves a bare `:` next to `date`, which Postgres rejects.
Same query rewritten with the function form `date(completed_at)`
avoids the lexer collision. Verified against the live DB via EXPLAIN
before pushing.
Lesson for future: tests in internal/services/ don't exercise the SQL
path because there's no DB fixture in the service-layer unit tests.
EXPLAIN-against-live or a real DB integration test is the only way to
catch this kind of SQL regression. Filing as architecture follow-up.
