Yes, that was a typo. > wouldn't the above be sufficient to create a DSM segment containing > a flexible array? Yes, it creates it, but can I initialize it properly in foo_init_state? How can I set the size member to the proper array size, and how can I zero-initialize the array with the correct length in it? What I can do currently is: 1. create the lwlock and set size to 0 in foo_init_state 2. take the lwlock after GetNamedDSMSegment returns 3. if size is 0 set it properly and zero-initialize the array That's why I said that there is a workaround, but it would be nicer if I could do it properly in the init callback, by passing the array size as a parameter to it.
