Function EncodeRestrictedSQLIdent

postgres/parser/lex/encode.go:165–171

EncodeRestrictedSQLIdent writes the identifier in s to buf. The identifier is quoted if either the flags ask for it, the identifier contains special characters, or the identifier is a reserved SQL keyword.

(buf *bytes.Buffer, s string, flags EncodeFlags)

// contains special characters, or the identifier is a reserved SQL
// keyword.
func EncodeRestrictedSQLIdent(buf *bytes.Buffer, s string, flags EncodeFlags) {
	if flags.HasFlags(EncBareIdentifiers) || (!isReservedKeyword(s) && isBareIdentifier(s)) {
		buf.WriteString(s)
		return
	}
	EncodeEscapedSQLIdent(buf, s)
}

// EncodeEscapedSQLIdent writes the identifier in s to buf. The
// identifier is always quoted. Double quotes inside the identifier
