Weasel 9.48.0, published today. Release notes: https://weasel.jasperfx.net/release-9-48

Nine PRs went into it: the parameter-type catch-all fix (weasel#758/#759 → #760) and the three issues it uncovered (#761, #762, #763), three SQL Server bugs found from Polecat (#764, #765, #766), MySqlConnector 2.6.1 for GHSA-473q-m89c-ghf8 (#767) and JasperFx 2.98.0 (#769).

Two behaviour changes upstream, neither of which this repo trips:

1. An unmapped type now defers instead of being guessed at, so ToParameterType throws for one where it returned a character catch-all; and a DateTime parameter binds as DateTime2 rather than a date-only type that dropped the time of day. The generated column type is unchanged, so no schema diff.
2. An enum binds as an integer unless told its EnumStorage, with new overloads taking one. Affects an AsString consumer on MySQL or Oracle only.

What reaches Marten

Three of the six issues are SQL Server only and inert here.

• weasel#758/Query by different id member #759 — PostgreSQL was one of the two providers that already fell through correctly, so the resolution behaviour Marten sees is unchanged. The part that was a hard failure rather than a slow query: both AddParameters overloads resolved through ToParameterType on the type, going around the value-aware seam weasel#403 added for Npgsql, so a UTC DateTime in a parameter bag was bound as timestamp without time zone and Npgsql threw outright, while the same value through AddNamedParameter worked.
• weasel#764 — PostgreSQL's numeric arm in PartitionExtensions.FormatSqlValue rendered with the current culture: a decimal partition bound carried a comma separator under de-DE, and a negative one a U+2212 minus sign under sv-SE, fi-FI, lt-LT or nb-NO. The date arms were already invariant with a comment saying why, which is exactly what made the numeric one read as deliberate. Marten's tenant and list partitions are string bounds, so this bites a numeric partition bound only.
• weasel#761 — PostgreSQL keeps Integer for an int-backed enum. One difference: an enum now resolves through its underlying type, so a long-backed enum gives Bigint rather than silently narrowing to Integer.
• Inert: weasel#762, delay document mapping validation until store construction - fixes #743 #763, default index on DocumentTypeColumn #765, Add index on column doc_type, see #765 #766.

I checked the call sites rather than assuming: RuntimeCompiledQueryDescriptorFactory and PostgresStorageDialect call ToParameterType and both pass types Npgsql maps; StoreOptions.Identity and ExecuteSqlStorageOperation use TryGetDbType, which still returns null for an unmapped type.

Verification

No Marten code changes. dotnet restore and dotnet build src/Marten.slnx clean against the published packages (not a local pack), 0 errors. The JasperFx 2.98.0 floor Weasel.Core now declares was already satisfied by #5801.
