Here is an updated list of nearly every PostgreSQL data type, and PHP's internal C-type equivalent, updated for PostgreSQL 9.2. The first array maps PHP's internal data type to PostgreSQL's equivalents. The second maps PostgreSQL's data-types to PHP's equivalents.

pg_field_type
(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
pg_field_type — 返回相应字段编号的类型名称
说明
pg_field_type() 返回字符串，其中包含指定 result 实例中指定 field 的基本类型名称。
注意:
如果字段使用 PostgreSQL domain（而不是基本类型），则返回的是 domain 的底层类型名称，而不是 domain 本身的名称。
注意:
本函数以前的名字为 pg_fieldtype()。
返回值
包含字段类型的基本名称的 string。
更新日志
| 版本 | 说明 |
|---|---|
| 8.1.0 |
现在 result 参数接受 PgSql\Result
实例，之前接受 resource。

示例
示例 #1 获取字段信息
<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
// 假设 'title' 是 varchar 类型
$res = pg_query($dbconn, "select title from authors where author = 'Orwell'");
echo "Title field type: ", pg_field_type($res, 0);
?>以上示例会输出：
Title field type: varchar
参见
- pg_field_prtlen() - 返回打印的长度
- pg_field_name() - 返回字段名
- pg_field_type_oid() - Returns the type ID (OID) for the corresponding field number

Also be aware that postgreSQL array fields will prefix the type name with an underscore (e.g. "_int4" or "_text"), while composite a.k.a. row-type fields will return type "record".

The types returned are:
bool
int2 (smallint)
int4
int8 (bigint)
numeric
float4 (real / float)
float8 (double)
timestamp
date
time
varchar
bpchar (fixed leng string, 'blank padded char')
inet (ip address)
money
There are some other more esoteric types, e.g. 'circle', but these are the most common.

Because complete documentation is always helpful, here are all the PostgreSQL general purpose types as they are listed in the 8.1 documentation, and each corresponding string returned by pg_field_type().
bigint => int8
bigserial => int8
bit => bit
bit varying => varbit
boolean => bool
box => box
bytea => bytea
character varying => varchar
character => bpchar
cidr => cidr
circle => circle
date => date
double precision => float8
inet => inet
integer => int4
interval => interval
line => line
lseg => lseg
macaddr => macaddr
money => money
numeric => numeric
path => path
point => point
polygon => polygon
real => float4
smallint => int2
serial => int4
text => text
time => time
time with time zone => timetz
timestamp => timestamp
timestamp with time zone => timestamptz
And for the record... (note the 7.4 client lib)
# postmaster --version
postmaster (PostgreSQL) 8.0.4
# ldd libphp4.so
...
libpq.so.3 => /usr/lib/libpq.so.3 (0xb7ac8000)
...
