SPI_repalloc — reallocate memory in the upper executor context
void * SPI_repalloc(void *pointer, Sizesize)
SPI_repalloc changes the size of a memory
segment previously allocated using SPI_palloc.
This function is no longer different from plain
repalloc. It's kept just for backward
compatibility of existing code.
void * pointerpointer to existing storage to change
Size sizesize in bytes of storage to allocate
pointer to new storage space of specified size with the contents copied from the existing area
