 The string to prefix to the unique branch ID when provisioning the PostgreSQL schema for a branch. Per [the PostgreSQL documentation](https://www.postgresql.org/docs/16/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS), this string must begin with a letter or underscore.
 
 Note that a valid prefix is required, as the randomly-generated branch ID alone may begin with a digit, which would not qualify as a valid schema name.
