備考 †

/*-------------------------
* StringInfoData holds information about an extensible string.
*		data	is the current buffer for the string (allocated with palloc).
*		len		is the current string length.  There is guaranteed to be
*				a terminating '\0' at data[len], although this is not very
*				useful when the string holds binary data rather than text.
*		maxlen	is the allocated size in bytes of 'data', i.e. the maximum
*				string size (including the terminating '\0' char) that we can
*				currently store in 'data' without having to reallocate
*				more space.  We must always have maxlen > len.
*		cursor	is initialized to zero by makeStringInfo or initStringInfo,
*				but is not otherwise touched by the stringinfo.c routines.
*				Some routines use it to scan through a StringInfo.
