In `@cmd/plancorpus/capture.go`:
- Line 305: Update the capture flow around record.SQL and record.Params so
generated bindings from translation.Parameters are merged into record.Params
before assigning sqlQuery.Statement to record.SQL. Preserve existing
query.Params while ensuring replaying PlanRecord.SQL with PlanRecord.Params
includes bindings such as `@__strlit0`.
In `@cypher/models/pgsql/format/format.go`:
- Around line 92-95: Update formatLiteral’s formatter selection to route
[]string values to formatSlice, while preserving formatStringLiteralParameter
for string values and formatValue for other types. This must allow TextArray
literals preserved by AsLiteral to produce parameterized PostgreSQL text arrays
instead of an unsupported literal type error.

Preserve generated bindings with captured SQL.
record.Params contains only query.Params, while generated bindings such as @__strlit0 are merged only into translation.Parameters. If PlanRecord.SQL and PlanRecord.Params are replayed together, record.Params lacks those bindings. Merge the generated parameters into record.Params before storing record.SQL.

Route []string values to formatSlice.
AsLiteral preserves []string and assigns TextArray. formatLiteral then sends the value to formatValue, which has no case []string, so it returns unsupported literal type instead of producing a parameterized PostgreSQL text array.
Proposed fix

return formatSlice(builder, typedValue, pgsql.Int8Array)
