ERROR: invalid memory alloc request size 0

John Hagstrand

Hello,

I'm getting the following error when I try to update or insert into a table.
This just started happening today. The table has been working fine up to
now. The table has 27,000 rows and 24 columns.

ERROR: invalid memory alloc request size 0

Why does this happen? And how can I work around it?

Thanks
John

What PG version is this, and what exactly is the table schema (and how
did you change it recently)? And let's see an exact example of a
failing query. It'd be even nicer if you could get a stack trace from
the errfinish call.

The only recent bugs of this ilk that I can recall had to do with
operations on zero-column tables. Probably you've found some new
corner case, but there's not enough info here to guess what.

A way to get aligned allocated memory?

by: serikas | last post by:

Is there a way to get aligned dynamically allocated memory? (provided that the requested memory size is a power of 2.) For example, if I request 128 bytes of memory, can I implement an allocator that allocates 128 bytes with 128-byte alignment? Of course I know that it is possible by allocating twice the requested size or more, but I would like to know if it is possible without excessive memory allocation.
