Answer 1

I've been trying to install pgsql on a plain Amazon Linux EC2 instance, and have been getting this error. Per Nicolás answer, I installed his suggested list of packages, but I continued to get the error. Looking more closely at the error, I noticed that the gcc command was including pgsql93 files:

gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -fPIC -DPSYCOPG_DEFAULT_PYDATETIME=1 -DPSYCOPG_VERSION="2.6.1 (dt dec pq3 ext lo64)" -DPG_VERSION_HEX=0x09030A -DHAVE_LO64=1 -I/usr/include/python2.7 -I. -I/usr/include/pgsql93 -I/usr/include/pgsql93/server -c psycopg/psycopgmodule.c -o build/temp.linux-x86_64-2.7/psycopg/psycopgmodule.o -Wdeclaration-after-statement

Looking in /usr/include/ I see pgsql92/ but not pgsql93/. So I took a look at what pgsql-related yum packages were installed and I noticed these:

postgresql92.x86_64 postgresql92-devel.x86_64 postgresql92-libs.x86_64 postgresql93.x86_64 postgresql93-libs.x86_64

Seemed to me like there ought to be a postgresql93-devel, so I tried:

sudo yum install postgresql93-devel

And that fixed the problem for me! So I guess the theme is: Look at the gcc call, and see what dir it's pulling in. Follow the crumbs from there.
