Descrizione

🐛 Bug supabase/cli

Affected area: Migrations

Supabase CLI version: current develop (d38ccd7e)

Operating system: Any. Reproduced with a unit test on Linux.

Installation method: Built from source

Command

supabase db push

Actual output

A migration containing this statement fails with a syntax error:

select E'it\'s; here';

The CLI splits the statement at the semicolon inside the string literal and sends select E'it\'s and here' as two statements.

Expected behavior

The statement is sent as one statement. In an escape string constant, \' is an escaped quote and does not end the literal.

Steps to reproduce

  1. Add a migration that contains select E'it\'s; here';.
  2. Run supabase db push against a database.
  3. See the syntax error caused by the split statement.

Additional context

The splitter in apps/cli/src/command-internal/sql-split.ts only treats a doubled quote as an escape inside single-quoted strings. PostgreSQL also accepts backslash escapes in E'...' strings, so the first \' is read as the end of the literal. A unit test for splitAndTrim fails on develop and passes when backslash escapes are honored for escape string constants only. Standard strings such as 'a\' are unchanged. The same splitter is used by seed files and the declarative schema commands.

I have a fix with a unit test ready and can open a PR if this is open for contribution.
