What

insert and upsert with a JsonArray body send the keys of the rows as the columns query parameter, joined without quotes. PostgREST only accepts unquoted names made of letters, digits, _, $ and spaces, and it trims surrounding spaces (pIdentifier in src/library/PostgREST/ApiRequest/QueryParams.hs). A table with a column like price (usd) or a.b gets a PGRST100 parse error on insert and upsert, and a column with leading or trailing spaces is matched against the trimmed name.

supabase-js, supabase-swift and supabase-flutter quote every name here, so the same table works from those clients.

Fix

Wrap each column name in double quotes in both places that build columns. Quoted names are matched exactly, so plain names like data resolve to the same column as before.

Tests

• testInsertValues and testUpsertValues now expect "data".
• testInsertQuotesColumnNames and testUpsertQuotesColumnNames send price (usd) and a.b.

The 4 tests fail without the fix. All 198 Postgrest JVM tests pass with it, and detekt is clean.

No public API change.
