Agreed, but I don't care for your proposed solution (put it in
libpgport) because that assumes a fact not in evidence, namely that
external projects have access to libpgport either.
Is it possible to put enough stuff in pg_crc.h so that external code could
just include that, perhaps after an extra #define to enable extra code?
In the worst case we could just do
#ifdef PROVIDE_CRC_IMPLEMENTATION
... current contents of pg_crc.c ...
#endif
but perhaps there's some intermediate possibility that's less ugly.
As for whether we could drop the existing near-duplicate code in
contrib/, I think we'd first have to convince ourselves that it was
functionally identical, because otherwise replacing those versions would
break existing ltree and hstore indexes.
