Stefan showed me via Jabber this warning:
/tmp/ccM7MfqX.s: Assembler messages:
/tmp/ccM7MfqX.s:703: Warning: 00000003fffffffc shortened to 00000000fffffffc
/tmp/ccM7MfqX.s:738: Warning: 00000003fffffffc shortened to 00000000fffffffc
He says that this comes from trgm_op.c file. I don't get the warning
myself obviously, so I started guessing.
3FFFFFFFC = 1111111111111111111111111111111100FFFFFFFC = 11111111111111111111111111111100
So the upper 2 bits are being lost (the second number is 32 bits wide).
The only thing that I think is related is the usage of VARSIZE(). It
looks like 0x3FFFFFFF (actual constant in the toast code) is shift two
bits left. I can see no such operation though.
