解决 ：error while loading shared libraries: libpq.so.5: cannot open shared object file: No such file or directory

1）首先确认 so存在。

2）之后用ldd 查看连接关系
我的环境下，地址是：/usr/lib64/postgresql-9.3/lib64

例如：/opt/postgresql/postgresql/lib # ldd /opt/postgresql/postgresql/bin/createdb

linux-gate.so.1 => (0x77f2f000)

libpq.so.5 => not found

libz.so.1 => /usr/lib/libz.so.1 (0x00698000)

libreadline.so.5 => /usr/lib/libreadline.so.5 (0x037f1000)

libtermcap.so.2 => /lib/libtermcap.so.2 (0x004e0000)

libcrypt.so.1 => /lib/libcrypt.so.1 (0x03006000)

libdl.so.2 => /lib/libdl.so.2 (0x00650000)

libm.so.6 => /lib/libm.so.6 (0x00656000)

libc.so.6 => /lib/libc.so.6 (0x00509000)

/lib/ld-linux.so.2 (0x004e6000)

3）配置vi /etc/ld.so.conf

加入 比bin的路径

4）执行ldconfig
