Hi all! I'm trying to run madlib's linear regression on a table with a group by
column for a client engagement. There are 44.5M distinct values in the group by
column and 14 data points for each group by value. Each regression should be
very simple since its only 14 points but I'm getting an error:
{code}
Function "madlib.linregr_merge_states(madlib.bytea8,madlib.bytea8) is
improperly aligned for alignment request in seek()"
{code}
Tested it on a few rows and it worked. Any idea what might be causing this
error or what this error means?
