Per the docs (15.4 Installation Procedure, Client-only installation), after running make, the following should work:
gmake -C src/bin install
gmake -C src/include install
gmake -C src/interfaces install
gmake -C doc install
However, it fails on the first command:
[postgresql-9.3.2]$ sudo gmake -C src/bin install
gmake: Entering directory `/opt/postgresql-9.3.2/src/bin'
gmake -C initdb install
gmake[1]: Entering directory `/opt/postgresql-9.3.2/src/bin/initdb'
gmake -C ../../../src/port all
[successful stuff cut here]
/bin/mkdir -p '/usr/local/pgsql-9.3.2/bin'
/usr/bin/install -c psql '/usr/local/pgsql-9.3.2/bin/psql'
/usr/bin/install -c -m 644 ./psqlrc.sample '/usr/local/pgsql-9.3.2/share/psqlrc.sample'
/usr/bin/install: cannot create regular file `/usr/local/pgsql-9.3.2/share/psqlrc.sample': No such file or directory
gmake[1]: *** [install] Error 1
gmake[1]: Leaving directory `/opt/postgresql-9.3.2/src/bin/psql'
gmake: *** [install-psql-recurse] Error 2
gmake: Leaving directory `/opt/postgresql-9.3.2/src/bin'
The directory 'share' does not exist, which seem to be the issue. Is there a missing dependency somewhere?
It appears the doc install correctly creates 'share', so installing src/bin last works.
