Bug reference: 14696
Logged by: Hiep Pham
Email address: hieppso194@gmail.com
PostgreSQL version: 10beta1
Operating system: Ubuntu 16.04
Description:
I am trying injecting true cardinality to Postgresql optimizer. To do that,
i calculate the return rows and total rows; then divide the first for the
second one. When use Load extension, postgreSQL throws the error:
pg_true_cardinality_extension.so: undefined symbol: PGfinish
Although, i included libpq to my source file and can make it to so file. But
when load to Postgresql, it can't link to libpq.
