Module identifiers 

Functions

is_safe_ident

True if name is a safe SQL identifier candidate (alphanumeric + underscore, non-empty, does not start with a digit). Loosely the same predicate as is_safe_unquoted minus the case sensitivity and reserved-word check — kept as a separate helper because it’s a generic “could this be a safe identifier” question used by filename validation.

is_safe_unquoted

True when name is safe to emit unquoted in SQL for the given dialect.

quote_ident

Quote a SQL identifier (table/column/schema) per database dialect, but only when quoting is syntactically required. Trivially-safe identifiers pass through untouched.

quote_ident_always

Always quote, regardless of safety. Doubles internal quote characters.

quote_qualified

Quote a qualified table reference (schema.table) per dialect, or the bare table when no schema is provided. Each part is conditionally quoted.
